Somebody from the UK told me once: We are like mushrooms. We are kept in
the dark, and once in a while we are allowed to see the light, and
somebody throws shit at us. In this case i get the same feeling.
Talking to Graham last night, we decided that at 90 knots there is very
little chance of flutter. But the load on the tailplane is minimal at that
speed. Now, if TP6 was loose, this was the time for the tail plane to move
out wards, disengage from the TP 12 pins and turn square to the direction
of flight, and so destroy itself, shake a wing loose and destroy the
plane. Not necessarily in that order. But as said,we are kept in the dark
and so on, so this is just another speculation.
