Aware
CONFiture and Barit,
I am well aware of the inertia and the slight descent before you achieve positive climb.
I am pretty sure that PBL is aware of that as well, but PBL posted a geometric puzzle as to how it would be possible that (as speculated) only the tail would have hit the ground without the landing gear (or in case of gear up) the engines hitting the ground as well (in the initial impact that would be).
