no, once airborne, the plane, already thinking it was airborne would do nothing new.
A LONG time ago, at KPIT, a DC9 took off with "bad" fuel and it landed as both engines flamed out on the departure runway. At that time, it was feeding both engines from the center tank...that is no longer done, now for obvious reasons.
so, in addition to my "airborne mode" theory, we must ask the configuration of the fuel pumps and which tank was supplying which engines...also the quality of fuel...by the way, this fuel theory isn't likely in my mind, but we have to ask.
ALWAYS let the plane fly itself off the ground. (unless!0) that is the surest way to get the right v speeds!
