Alan,
The on board instruments showed a
depth of 37,799 feet but this was revised up to 35,814 and in 1995 more
accurate surveys again revised this to the 35,797 according to the
online Wikipedia.

Hi David,
I thought it was 35,848 ft. The stuff about the wet boot
in the last quiz wasn't quite true,
but you did say to guess.

fact
On January 23rd, 1960 Jacques
Piccard and Lt. Don Walsh touched down in the Trieste in the deepest point
of the Mariana trench.
It took this craft
4 hours and 48 minutes just to descend the 35,797 feet. An underwater sonar
communications system which malfunctioned earlier in the voyage began again
to operate, and at this great depth and a message took 7 seconds to
travel to the surface support ship and another 7 seconds to receive the
reply!
A manned voyage to this
depth has never since been attempted although man has returned here with the
aid of robotics.
How long were
these two occupants at this deepest depth aboard the
Trieste?
