Why the hell is anyone taking the p!ss out of this guy?

It reminds me of Roland Free (not John Edgar as I originally put):
He did a record run of 150mph after removing his clothes and lying down to improve his aerodynamics
Absolutely bonkers but you've got to admire it!

Good luck to the fellow, he's a Burt Munro character by the sounds of it. We all need people like him.

Maybe his mistake was tacking the number 2000 mph next to it. Claiming you will as good as tripple the existing record will inevitably invite derision,

This is like me saying i fancy a shot at the 100m Olympic gold, with no prior training other than a light jog every so often, but then decide to take a gallon of steriods to aim to run it in under 4 seconds!
Actually, I reckon the olymics would be more interesting if perfomance enhancing drugs were allowed. there'd be russian weightlifters built like bears !
I would really like this guy to succeed and prove that with a modest amount of engineering skill, and a great deal of courage, you can succeed in a Hi-tech pursuit and set insurmountable records that make us all humbled at his achievements.
But it won't happen will it? - he will make a big hole in the ground somewhere, which is still brave, but dumb.

Like Top Gear, Ambitious but rubbish !But it won't happen will it? - he will make a big hole in the ground somewhere, which is still brave, but dumb.
Bloody yanks, they're always doing this, just find out what record the others are going for and say you can double it, didn't they do this with the last two or three Shelby Super Cars? They said, oh this one has double the Veryon's 1000bhp and will do 300mph, then they test it and it does 250mph and nearly kills everyone involved.
This is why they had to come to us to build a car that that would beat Ferrari at Le Mans.
Still, they did put a man on the moon and are the only nation to have ever used nuclear weapons in a conflict so we'll let that go...
If he even beats 1,000mph with his garden shed, horizontal X-15 while staying on the ground I will be very surprised, 2,000mph is laughable. It's important to set your sights high but he's just plucked a big number out of the air like a little kid in the school playground. There are only a handful of jets that have travelled faster than 2,000mph, SR-71 Blackbird, MiG 25 and MiG-31 Foxhound/bat. He has to do that with (four) contact patches of spinning metal in permanent contact with the salt/sand, that, incidentally will be passing under them at 900 metres every second.
By the way, the power needed to overcome air resistance is the cube of the velocity, so 2,000mph requires EIGHT times the power of 1,000mph. So if his vehicle has just half the frontal area or Drag co-efficient of Bloodhound SSC, he will still need four times the power, which he doesn't have.
Having a pretty CGI rendering/model doesn't lift him out of the camp of the idiot who strapped a SIdewinder to his car and ending up adorning the side of a mountain.
Having said all that, I wish him Good Luck and hope that he succeeds, at least in realising it's not going to happen while he's still alive, I certainly don't wish ill of him.

Genius is close to Madness but I think all he will achieve is a record number of You Tube hits when it all goes wrong.
I've read Milton Thompsons book on his time when he flew the X-15 and even NASA had trouble getting the XLR-99 to function properly. Sometimes they got 55,000lbs of thrust other times 60,000lbs and once in a while a brown trouser moment when the pilot got zero lbs of thrust.
The engine ran on liquid Ammonia which is nasty stuff, liquid Oxygen which helps everything burn just that little bit better and highly volatile Hydrogen Peroxide was used to power the fuel pump.
Also will he have enough room to accelerate then decelerate? I don't think so, one of the major problems with the X-15 was slowing it down so they could land it.
Milt Thompson describes how in a 45deg climb the X-15 was accelerating at 4G which was so hard he could feel the tendons holding his heart in place stretch.

I think you're missing the point - I'm certainly up for seeing someone do it, as are pretty much all here. It is the slightly unrealistic approach that is what is being commented on. Sure the guy is pushing the boundaries but it is a very, very big stretch from the current 763 record (peaked at 771) up to 2000.try reading up on him...

The last picture I saw of sonic wind looked like this:
http://www.racecar-engineering.com/wp-content/uplo...
The SSC team only just got their record and were very nearly beaten to it by an australian team, there was an awful lot of luck involved. Things like the lower surfaces of the body getting caked in salt resulting in increasing mass, disrupting the control surfaces and wheels.
There are other contenders too. The same Aussie team is back with a revised engine and vehicle (Aussie Invader 5R), then there is Jet Black (an attempt from New Zealand), Silver Bullet (another Australian attempt), a stray project called the Fossett LSR (currently up for sale if you have $3M to spare) and the North American Eagle.

he has the rockets that are capable of 4500mph in the air, so the capability is there.
this is not like you going for the olmypic gold though with no training. This is a guy who has spent his life breaking speed records, now has the hardware to do it and obviously has a lot of expertise.
If he has been to 763mph before then he obviously has the technical knowledge and skills to get past the issues of stability you would encounter long before this. of course there will be more issues all the way to 2000mph, but breaking records is not about multimillion dollar computer simulations, it is about getting out there and trying it.
there is a very high chance he will die, he has the same problems as faced by the blackbird crew as well as all the others.
so a load of internet warriors who have seen the Fastest Indian, and sole knowledge is based upon a wikipedia article would be well advised to stop being such pricks about such an individual.

Why are you comparing the top speed of a rocket powered car, to a jet powered aircraft, then commenting how it's unlikely to happen.
If you want to compare it to aircraft, compare it to rocket powered ones. You'll find a fair few of them, especially if you include missiles, have went substantially faster than that.
I'm not saying i think this guy is going to get this working, but lets get our facts right.
You missed my point entirely, the propulsion system is irrelevant, there is no doubting that you can make something go 2,000mph with a rocket, it's the myriad other problems that arise when you get close to those speeds, in the air.If you want to compare it to aircraft, compare it to rocket powered ones. You'll find a fair few of them, especially if you include missiles, have went substantially faster than that.
I'm not saying i think this guy is going to get this working, but lets get our facts right.
Missiles? Oh dear, aren't too many of those that are in constant contact with the ground are there? Oh, and with an American sitting inside holding a steering wheel?

I'd advise skipping to 1:50 secs though to avoid the boredom.
