create weightlessness when training future astronauts by causing the plane
to drop suddenly, so maybe it was going at 0 G's until it hit the desk???
I dunno... but it sure DID work! :-)))
Chris,
It wasn't the arc of motion, it was the sudden stop at the end! I dare
say, since I've been on the periphery of drop testing, that it was a little
more than 5g's of deceleration at the end of travel. If you have a very
hard desktop (e.g. finished hardwood) it would be at least an order of
magnitude more than 5g's. It's quite a force you exerted on that camera
body and _why_ I advise _never_ dropping a camera or lens to a hard
surface. The forces on impact are enormous. The energy dissipation occurs
in an infinitessimally short length of time.
