As well as the particular airplane in the situation. | |

I see the problem. You don't know what velocity is. It's a VECTOR. It
changes when you turn. If you don't understand this there's not much
point talking about anything that involves physics....

I agree. And it could be a place to go.
I was just saying that a mall/strip center parking lot isn't necessarily
the "ah...I'll go there!" place. Even at 7 a.m., there can be cars and
people everywhere. | |

So much that you mix up speed and velocity? LOL!

Nope. Not even at high school. The magnitude is "speed".

Gosh, this isn't a technical forum? Was my post not including
"technical" terms like acceleration?

What does "flying with the wind" imply to you, a direction or a speed?
I'd say the former but I'm only a native English speaker.

I thought the engine had stopped?

BS. This is stated in any basic physics text book -even Wiki knows it:
"In physics...The scalar absolute value (magnitude) of velocity is
speed."

No, don't think the engine quit. They said it was smoking on takeoff,
and witnesses who saw it come down described how the engine sounded, so
it apparently was still running. | |

Well first ya got to turn back and then you have to turn to line up
with the runway...
