Underwater take off of F15 fighter jet

>> ^arekin:
there is a good reason that jets don't take off vertically.


Because it is unstable and it uses a lot of fuel. But an F-15 could otherwise take off vertically, with a thrust to weight ratio as high as 1.6 with afterburners going. I'm not sure it could actually achieve that thrust while stationary, though.

Afterburners of course don't work without substantial air compression. The air is compressed when the plane is travelling really fast, say 500mph. Even if an F-15 could control the vertical takeoff (no way in hell with no control surfaces or nose rockets), it would never have the thrust from a standstill.


Also, this has to be a dupe. It is ancient video...
