This is just an extract from a book by Brian Shul, who flew the SR-71.. I think thats all we need to know biggrin

Sled Drive said:
There were a lot of things we couldn't do in an SR-71, but we were the fastest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the jet. Fun would not be the first word I would use to describe flying this plane. Intense, maybe. Even cerebral. But there was one day in our Sled experience when we would have to say that it was pure fun to be the fastest guys out there, at least for a moment.

It occurred when Walt and I were flying our final training sortie. We needed 100 hours in the jet to complete our training and attain Mission Ready status. Somewhere over Colorado we had passed the century mark. We had made the turn in Arizona and the jet was performing flawlessly. My gauges were wired in the front seat and we were starting to feel pretty good about ourselves, not only because we would soon be flying real missions but because we had gained a great deal of confidence in the plane in the past ten months. Ripping across the barren deserts 80,000 feet below us, I could already see the coast of California from the Arizona border. I was, finally, after many humbling months of simulators and study, ahead of the jet.

I was beginning to feel a bit sorry for Walter in the back seat. There he was, with no really good view of the incredible sights before us, tasked with monitoring four different radios. This was good practice for him for when we began flying real missions, when a priority transmission from headquarters could be vital. It had been difficult, too, for me to relinquish control of the radios, as during my entire flying career I had controlled my own transmissions. But it was part of the division of duties in this plane and I had adjusted to it. I still insisted on talking on the radio while we were on the ground, however. Walt was so good at many things, but he couldn't match my expertise at sounding smooth on the radios, a skill that had been honed sharply with years in fighter squadrons where the slightest radio miscue was grounds for beheading. He understood that and allowed me that luxury. Just to get a sense of what Walt had to contend with, I pulled the radio toggle switches and monitored the frequencies along with him. The predominant radio chatter was from Los Angeles Center, far below us, controlling daily traffic in their sector. While they had us on their scope (albeit briefly), we were in uncontrolled airspace and normally would not talk to them unless we needed to descend into their airspace.

We listened as the shaky voice of a lone Cessna pilot asked Center for a readout of his ground speed.

Center replied: "November Charlie 175, I'm showing you at ninety knots on the ground."

Now the thing to understand about Center controllers, was that whether they were talking to a rookie pilot in a Cessna, or to Air Force One, they always spoke in the exact same, calm, deep, professional, tone that made one feel important. I referred to it as the "HoustonCenterVoice." I have always felt that after years of seeing documentaries on this country's space program and listening to the calm and distinct voice of the HoustonCenterControllers, that all other controllers since then wanted to sound like that... and that they basically did. And it didn't matter what sector of the country we would be flying in, it always seemed like the same guy was talking. Over the years that tone of voice had become somewhat of a comforting sound to pilots everywhere. Conversely, over the years, pilots always wanted to ensure that, when transmitting, they sounded like Chuck Yeager, or at least like John Wayne. Better to die than sound bad on the radios.

Just moments after the Cessna's inquiry, a Twin Beech piped up on frequency, in a rather superior tone, asking for his ground speed.

"Ah, Twin Beach: I have you at one hundred and twenty-five knots of ground speed."

Boy, I thought, the Beechcraft really must think he is dazzling his Cessna brethren.

Then out of the blue, a Navy F-18 pilot out of NAS Lemoore came up on frequency. You knew right away it was a Navy jock because he sounded very cool on the radios.

"Center, Dusty 52 ground speed check."

Before Center could reply, I'm thinking to myself, hey, Dusty 52 has a ground speed indicator in that million dollar cockpit, so why is he asking Center for a readout? Then I got it -- ol' Dusty here is making sure that every bug smasher from Mount Whitney to the Mojave knows what true speed is. He's the fastest dude in the valley today, and he just wants everyone to know how much fun he is having in his new Hornet.

And the reply, always with that same, calm, voice, with more distinct alliteration than emotion:

"Dusty 52, Center, we have you at 620 on the ground."

And I thought to myself, is this a ripe situation, or what? As my hand instinctively reached for the mic button, I had to remind myself that Walt was in control of the radios. Still, I thought, it must be done -- in mere seconds we'll be out of the sector and the opportunity will be lost. That Hornet must die, and die now.

I thought about all of our Sim training and how important it was that we developed well as a crew and knew that to jump in on the radios now would destroy the integrity of all that we had worked toward becoming. I was torn. Somewhere, 13 miles above Arizona, there was a pilot screaming inside his space helmet.

Then, I heard it. The click of the mic button from the back seat. That was the very moment that I knew Walter and I had become a crew. Very professionally, and with no emotion, Walter spoke:

"Los Angeles Center, Aspen 20, can you give us a ground speed check?"

There was no hesitation, and the reply came as if was an everyday request:

"Aspen 20, I show you at one thousand eight hundred and forty-two knots, across the ground."

I think it was the forty-two knots that I liked the best, so accurate and proud was Center to deliver that information without hesitation, and you just knew he was smiling. But the precise point at which I knew that Walt and I were going to be really good friends for a long time was when he keyed the mic once again to say, in his most fighter-pilot-like voice:

"Ah, Center, much thanks. We're showing closer to nineteen hundred on the money."

For a moment Walter was a god. And we finally heard a little crack in the armor of the HoustonCentervoice, when L.A. came back with,

"Roger that Aspen, Your equipment is probably more accurate than ours. You boys have a good one."

It all had lasted for just moments, but in that short, memorable sprint across the southwest, the Navy had been flamed, all mortal airplanes on freq were forced to bow before the King of Speed, and more importantly, Walter and I had crossed the threshold of being a crew. A fine day's work.

We never heard another transmission on that frequency all the way to the coast. For just one day, it truly was fun being the fastest guys out there.
Sled Driver said:
In April 1986, following an attack on American soldiers in a Berlin disco, President Reagan ordered the bombing of Muammar Qaddafi's terrorist camps in Libya. My duty was to fly over Libya and take photos recording the damage our F-111's had inflicted. Qaddafi had established a "line of death," a territorial marking across the Gulf of Sidra, swearing to shoot down any intruder that crossed the boundary. On the morning of April 15, I rocketed past the line at 2,125 mph.

I was piloting the SR-71 spy plane, the world's fastest jet, accompanied by Maj Walter Watson, the aircraft's reconnaissance systems officer (RSO). We had crossed into Libya and were approaching our final turn over the bleak desert landscape when Walter informed me that he was receiving missile launch signals. I quickly increased our speed, calculating the time it would take for the weapons-most likely SA-2 and SA-4 surface-to-air missiles capable of Mach 5 - to reach our altitude. I estimated that we could beat the rocket-powered missiles to the turn and stayed our course, betting our lives on the plane's performance.

With the Libyan coast fast approaching now, Walt asks me for the third time, if I think the jet will get to the speed and altitude we want in time. I tell him yes. I know he is concerned. He is dealing with the data; that's what engineers do, and I am glad he is. But I have my hands on the stick and throttles and can feel the heart of a thoroughbred, running now with the power and perfection she was designed to possess. I also talk to her. Like the combat veteran she is, the jet senses the target area and seems to prepare herself.

For the first time in two days, the inlet door closes flush and all vibration is gone. We've become so used to the constant buzzing that the jet sounds quiet now in comparison. The Mach correspondingly increases slightly and the jet is flying in that confidently smooth and steady style we have so often seen at these speeds. We reach our target altitude and speed, with five miles to spare. Entering the target area, in response to the jet's new-found vitality, Walt says, "That's amazing" and with my left hand pushing two throttles farther forward, I think to myself that there is much they don't teach in engineering school.

Out my left window, Libya looks like one huge sandbox. A featureless brown terrain stretches all the way to the horizon. There is no sign of any activity. Then Walt tells me that he is getting lots of electronic signals, and they are not the friendly kind. The jet is performing perfectly now, flying better than she has in weeks. She seems to know where she is. She likes the high Mach, as we penetrate deeper into Libyan airspace. Leaving the footprint of our sonic boom across Benghazi, I sit motionless, with stilled hands on throttles and the pitch control, my eyes glued to the gauges.

Only the Mach indicator is moving, steadily increasing in hundredths, in a rhythmic consistency similar to the long distance runner who has caught his second wind and picked up the pace. The jet was made for this kind of performance and she wasn't about to let an errant inlet door make her miss the show. With the power of forty locomotives, we puncture the quiet African sky and continue farther south across a bleak landscape.

Walt continues to update me with numerous reactions he sees on the DEF panel. He is receiving missile tracking signals. With each mile we traverse, every two seconds, I become more uncomfortable driving deeper into this barren and hostile land. I am glad the DEF panel is not in the front seat. It would be a big distraction now, seeing the lights flashing. In contrast, my cockpit is "quiet" as the jet purrs and relishes her new-found strength, continuing to slowly accelerate.

The spikes are full aft now, tucked twenty-six inches deep into the nacelles. With all inlet doors tightly shut, at 3.24 Mach, the J-58s are more like ramjets now, gulping 100,000 cubic feet of air per second. We are a roaring express now, and as we roll through the enemy's backyard, I hope our speed continues to defeat the missile radars below. We are approaching a turn, and this is good. It will only make it more difficult for any launched missile to solve the solution for hitting our aircraft.

I push the speed up at Walt's request. The jet does not skip a beat, nothing fluctuates, and the cameras have a rock steady platform. Walt received missile launch signals. Before he can say anything else, my left hand instinctively moves the throttles yet farther forward. My eyes are glued to temperature gauges now, as I know the jet will willingly go to speeds that can harm her. The temps are relatively cool and from all the warm temps we've encountered thus far, this surprises me but then, it really doesn't surprise me. Mach 3.31 and Walt is quiet for the moment.

I move my gloved finder across the small silver wheel on the autopilot panel which controls the aircraft's pitch. With the deft feel known to Swiss watchmakers, surgeons, and "dinosaurs" (old- time pilots who not only fly an airplane but "feel it"), I rotate the pitch wheel somewhere between one-sixteenth and one-eighth inch location, a position which yields the 500-foot-per-minute climb I desire. The jet raises her nose one-sixth of a degree and knows, I'll push her higher as she goes faster. The Mach continues to rise, but during this segment of our route, I am in no mood to pull throttles back.

Walt's voice pierces the quiet of my cockpit with the news of more missile launch signals. The gravity of Walter's voice tells me that he believes the signals to be a more valid threat than the others. Within seconds he tells me to "push it up" and I firmly press both throttles against their stops. For the next few seconds, I will let the jet go as fast as she wants. A final turn is coming up and we both know that if we can hit that turn at this speed, we most likely will defeat any missiles. We are not there yet, though, and I'm wondering if Walt will call for a defensive turn off our course.

With no words spoken, I sense Walter is thinking in concert with me about maintaining our programmed course. To keep from worrying, I glance outside, wondering if I'll be able to visually pick up a missile aimed at us. Odd are the thoughts that wander through one's mind in times like these. I found myself recalling the words of former SR-71 pilots who were fired upon while flying missions over North Vietnam. They said the few errant missile detonations they were able to observe from the cockpit looked like implosions rather than explosions. This was due to the great speed at which the jet was hurling away from the exploding missile.

I see nothing outside except the endless expanse of a steel blue sky and the broad patch of tan earth far below. I have only had my eyes out of the cockpit for seconds, but it seems like many minutes since I have last checked the gauges inside. Returning my attention inward, I glance first at the miles counter telling me how many more to go, until we can start our turn. Then I note the Mach, and passing beyond 3.45, I realize that Walter and I have attained new personal records. The Mach continues to increase. The ride is incredibly smooth.

There seems to be a confirmed trust now, between me and the jet; she will not hesitate to deliver whatever speed we need, and I can count on no problems with the inlets. Walt and I are ultimately depending on the jet now - more so than normal - and she seems to know it. The cooler outside temperatures have awakened the spirit born into her years ago, when men dedicated to excellence took the time and care to build her well. With spikes and doors as tight as they can get, we are racing against the time it could take a missile to reach our altitude.

It is a race this jet will not let us lose. The Mach eases to 3.5 as we crest 80,000 feet. We are a bullet now - except faster. We hit the turn, and I feel some relief as our nose swings away from a country we have seen quite enough of. Screaming past Tripoli, our phenomenal speed continues to rise, and the screaming Sled pummels the enemy one more time, laying down a parting sonic boom. In seconds, we can see nothing but the expansive blue of the Mediterranean. I realize that I still have my left hand full-forward and we're continuing to rocket along in maximum afterburner.

The TDI now shows us Mach numbers, not only new to our experience but flat out scary. Walt says the DEF panel is now quiet, and I know it is time to reduce our incredible speed. I pull the throttles to the min 'burner range and the jet still doesn't want to slow down. Normally the Mach would be affected immediately, when making such a large throttle movement. But for just a few moments old 960 just sat out there at the high Mach, she seemed to love and like the proud Sled she was, only began to slow when we were well out of danger. I loved that jet.
How cool is that! I'd love the book, but..

I bought a copy of it a few years back when the exchange rate was a little better, along with a copy of "The Untouchables" from the same place. In my opinion if you're a fan of the Blackbird it's worth every penny (cent) for the photography in it alone.

Sometimes copies of the original smaller format version turn up on Ebay for a bit less.

Or just borrow it from your library like I did. Not worth the money though IMO. Very short, albeit with some nice pictures, and is more of a hardback coffee table flick through book.

I have my copy...

The SR71 Flight Manual can be found online here: http://www.sr-71.org/blackbird/manual/

The Mach limitation was not really a Mach limitation at all but a CIT limitation of 427C.

From Figure 5.4 in the manual you can see that in an environment of approximately ISA-10C, Mach 3.5 is possible with a CIT of 427C.

Today, I saw the opposite deviation, ISA+17C, somewhere over Northern Europe...

Thanks (& Jonny671) for the info. I'll shall make the effort then.

Back on topic: There is a good chapter on the SR-71 in Ben Rich's book "Skunk Works" and some other books by Paul F Crickmore, forgive me I can't remember the titles, but are an excellent read.
