Yes. For a 4' fall, we know it takes 1/2 a second to reach the
ground:
s = 1/2 a t^2 + v0 t + s0
s0 = 0, a = 32 f/s^2, v0 = 0, s = 4, solve for t gives 1/2 a second to
make the fall. Sos was saying 10's of ms to retract the heads, so
even a 300ms response time wouldn't be fatal, but it would be pushing
the limits.
For a 2' fall, you have even less time. More like 350ms. 1' is 250ms...
