It was said in a previous post that by not rotating on schedule, you would throw off your takeoff data but the airplane would still EVENTUALLY get off the ground. I agree with this idea because it is true. The Faster an airplane goes, more lift the wings make and eventually
given enough runway to do so (yes that could mean 15 miles or so, this is strictly hypothetical and not practical what-so-ever), any airplane,
if trimmed and configured properly will eventually develop enough life to get off the ground with no pilot input (assuming the wheels can take it up to said speed without falling off)
As for the F-16 in pure vertical flight, the wings are producing ZERO AERODYNAMIC FORCE except for drag, see the above post because he is correct. Regardless of the camber of a wing, you still have the capability to STOP it from creating any force Perpendicular to the Rel Wind by simply selecting an AOA that will yield zero aerodynamic force. Much like in a normal descent when a pilot reduces the AOA, thereby reducing lift to initiate a descent, in the case of pure vertical flight of a + cambered wing, the pilot simply holds the nose a few degrees nose down from directly vertical in order to reduce the AOA to the point where zero force is made (again, except for drag which is 100% countered by thrust). If the pilot did not do this, the airplane would actually travel horizontally across the ground (directly upward out of the canopy as seen by the pilot) while climbing vertically because the "lift" that is being created by the wings would pull the airplane in that direction.
