henra;

I was just considering the wing. The cw of a circular cylinder moving perpendicular to its axis at high Re is of the order of 0.4. But as you say,fair enough for a rough calculation. Shall we split the difference?

The BEA speaks about attitude and vertical speed. The latter is based on examination of elements recovered from the cabin, and on 'arm 36g'. Regarding horizontal speed, bear in mind BEA's description of the separation of the fin under longitudinal (horizontal) inertia loads.
