The shuttle stack bends not while the boosters ignite.. it bends because it is still hooked to the platform until the boosters ignite. Because the main engines are preliminary ignited, they already put a dynamic angled 'push forward' to the shuttle while the stack is still locked. Right after booster ignition, then the fixing clamps and all remaining connections are released.

Well...the shuttle as the engines ignite is being released by the holders...thus...the shuttle tanks are going to wobble a bit.

that is just a last goodbye wave

@berndpfe you guys googled this stuff didn't you

@jimgoss77 Columbia from STS-107. You can tell by the black wing chines and the NASA Meatball. Columbia only had the blue meatball markings for two launches, STS-109 and 107. And of the two, STS-109 was a night launch while 107 was daytime.

Known as "Orbiter Twang Phenomenon" and experienced during the 6 seconds between Main Engine Light and the Hold-down bolts blowing. It is exactly one meter. .

Wait, wait just a bit to the left. Okay now a bit to the right. Alright thats just about perfect.

it bends... but will it blend?!?
-
Yes It bends all material yields to stress steel aluminum titanium carbon fiber composites everything.That's engineering folks..

what shuttle is that.
I've heard this is used as part of the launch procedure in an effort to be as straight as an arrow, mathematically speaking. As soon as the shuttle rebounds to a certain point in its sway after the initial shock caused by the ignition of its engines, the shuttle is launched to achieve the proper trajectory.

Exactly, also if you look at the side view of a Space Shuttle launch, you'll see it actually launches up and forward, you can use the lightning mast on the top of the tower as a landmark to see how the shuttle changes position, then it begins the roll program. If the pad gimbled and rotated, that wouldn't be necessary, but its a big system...that would cost BILLIONS! hahaha.

You...are correct sir! You can see the black chines briefly...
as soon as it clears the tower, the vehicle easily reaches 150 miles per hour.
