So from a Science perspective what was learnt from this 'experiment', object dropped from plane....falls to earth. Oh I know... I can see the paper headlines now. 'Newtons law of Gravitation confirmed'
To be honest mate, you're getting a bit sad and tedious with this whole "Space Rockets Don't Belong In The Science Forum" schtick.Here's a suggestion. The next time you see a space rocket themed post in here, and your OCD goes hyper OC, open up a Javascript console in your browser and paste this into it:
$("body").children().each(function () {
$(this).html( $(this).html().replace(/Science!/g,"Science and Space Rockets!") );
});
There you go. This is now the "Science and Space Rockets!" forum, your OCD is assuaged, and we all live happily ever after.
Well said!
And politer than I would have been, too!
k you guys are not on my team, critical analysis and thinking go a long way and its fine should you wish to be rude to me, as long as there is a scientific basis for doing so

if you wished to discuss the the trajectories of a projectile with airdrop along with initial varying velocities it would be worthy of discussion within a science thread. As would displacement of parabolic throwing
Most of the threads regarding Rockets are oooooh, WOW, look at that... but nowt Science debate very little Science discussion Its like the Dark ages.
Why don't you wow us then, Mr. Scientist?Most of the threads regarding Rockets are oooooh, WOW, look at that... but nowt Science debate very little Science discussion Its like the Dark ages.
So far all I can see you've contributed to the thread is quoting some dodgy "records". Perhaps you'd like to start a fresh thread detailing the dynamics of atmospheric rocket flight, or a mathematically rigorous analysis of Pintle injector geometries?

Yeah, why bother with tests eh? Just light the blue touch paper and crack on, she'll be apples.

It wasn't an "experiment" it was a "function test" of the rocket carry and release mechanism that is now fitted to the on the 747 - and what they have learnt from it is that it works.There are all sorts of issues that need to be verified when designing loads that are to be dropped from below aircraft. As far as I know, the 747 has never been used before to drop stores from underneath its wings - so a number of test drops must be carried out to ensure that the load will fall away cleanly and not be affected by turbulence from the drop aircraft. The video linked above showing various stores drop tests that have gone wrong shows that the behaviour of a dropped load can be somewhat unpredictable.
I had a long chat with the Virgin guys at the Farnborough air show last year and they certainly know what they are talking about.

You’re lucky there even is a science forum, a few of us had to whinge for years to get one. We just had boats planes and trains before this. Imagine what it was like talking about rockets with that lot.if you wished to discuss the the trajectories of a projectile with airdrop along with initial varying velocities it would be worthy of discussion within a science thread.

Rockets definitely belong in the science forum.

I get why a Science thread, when science is being discussed. But Rockets are a means of transport just as planes trains and automobiles. The Science of those modes of transport could be discussed within a science thread. However much of the rocketeer stuff here has no Science content so why is a launch of a rocket ‘science’ rather than travel? where is the discernment? This may be the very reason it took so long to get a Science section...... I know I will get arsy responses but a Rocket launch is no more special than boaty mcboatface pulling out of harbour. Rockets definitely belong in the science forum.

Toaster must go down a storm at scientific conferences though - when he presents the same paper he's been repeatedly offering for 15 consecutive years, same old stuff, year in, year out, with a slightly different font and maybe a new bit of crayon work at the top.

Having said this MartG is spot on there should be a rocket thread.
A video of the drop test. You can see how pitched up the 747 is at the point of release.

The "rocket" was full of water and antifreeze, to simulate the weight of a fully fuelled rocket.

The movement up and away by the 747 would have been a deliberate manoeuvre to ensure that there was adequate separation from the falling load. When NASA used their 747 for the Shuttle drop tests in 1977 they also turned away from the separating load . However, in that situation the 747 dived away as their drop load came off the top of the 747 rather than from below.https://www.youtube.com/watch?v=wWaW3IzVGBw

The Virgin Orbit 747 "Cosmic Girl" met up for a formation flight with the Red Arrows over the Mojave desert, California.
This is part of their big North American tour. Their Hawks don't have the ability to refuel in the air, so they had to stop off in Iceland, Greenland and Newfoundland to get across the Atlantic.
They Royal Air Force are actually seconding a Typhoon pilot, Flight Lieutenant Stannard to Virgin Orbit.

Yes, it really shows off how big those Jumbos are too.
Here's some more pics of the event, plus other incredible stills and video from the Red Arrows' tour:
