Video of a Boeing 787 performing acrobatic stunts

I came across this video of a Boeing 787 performing acrobatic stunts and thought it was interesting.

You rarely see them moving like this for obvious reasons. Its practicing for the Farnborough Airshow.

I was thinking there might be a few plane watchers here that may find this fun to watch too.

Airliners can do quite a bit more than most people know. To keep passengers comfortable and happy they are flown within very tight limits, however.

Alvin Johnston rolled a 707 once, and a couple of others probably did similar things.

Now that I remember, didn't a 747 do an aileron roll once?

Not officially. What pilots did when alone with a craft we will never know for sure.

I didn't know planes that big could do that kind of stuff. It looks like an RC plane! :0.0:

AFAIK they are doing it all the time when they are testing new models. It's part of the testing process and the planes are required to be able to perform such maneuvers.

On the subject of an aircraft doing something you'd expect only an RC version capable of, I was impressed by the agility of the Westland Lynx helicopter.

I've never seen a helicopter do a full barrel roll before... or a backflip from stationary, for that matter...

Especially impressive considering the Lynx isn't an attack helicopter. It was designed as a transport helicopter, though it must have an obscene power to weight ratio to pull off those maneuvers.

Commercial transport planes are not required to be able to do rolls. Now, aileron rolls *properly executed* supposedly put no extra stress on the airframe, but most airliners are not rolled by test pilots - Tex Johnson did it to impress people, and actually almost got into trouble over it.

On the other hand, loops do add stress, but all that stress is in the direction the plane was built to take most of the load. A typical canvas and wood glider will do a loop, but falls apart when attempting a roll (or not doing a perfect one, which boils down to the same thing).

Tex Johnson's flight reportedly popped quite a few rivets out of the 707 he was flying.

On the topic of planes that look like they are RC, check out the Pugachev's Cobra. 120 degree AoA!

If the link breaks the timestamp, fast forward to 2min 35sec.
