A30yoyo,
There were a couple of runway overrun accidents with the Comet due to over rotation and wedge shaped pieces were added to the leading edges outboard of the engine intakes to cause airflow disruption over the tail, making it shake, if the pilot over rotated.
I believe the nose of one of those over rotation accidents,( Rome), was used in the Comet simulator that BOAC and eventually Dan Air had??
Your picture, given its position from the start of 28L, shows a good example of over rotation about to happen if he rotates any further.
V1 speed has all the wheels firmly on the ground, Vr is the rotate speed and then V2 etc. so this guy looks very premature unless he is at a very light weight?? But it could be before we used the V1, V2 etc, performance numbers??
