One other thing... it's essentially impossible to
stop a fixed-wing airplane in midair. (You can have zero ground speed due to headwinds, but not zero airspeed). If you try, the nose drops and it glides towards the ground. If you try to stop that, it will eventually perform an aerodynamic stall, which WILL make the nose drop, but it still won't come to a halt. About the only way to reach zero airspeed is to pull the plane into a near-vertical climb. And even then it reacts by dropping the nose and building up some speed again (or if you are truly vertical, it can fall tail-first and then it will at some point snap into a more normal posture and then start to fly nose-first again). It's fun to do though, in the right kind of airplane - a small aerobatic one - and with enough altitude. John |

John if it had been an airshow kind of situation I wouldn't have given it a thought but this was a commercial jet and it was over a populated area. No fun... Debbie |
