Does breathing 100% O2 from chocks to chocks help lower the N2 in
the body? In other words, is there a secondary benefit to breathing
100% O2 other than that you don't pass out?

Depends on the climb rate. The U2 presure suit has a fixed face plate
because the AC goes into a high rate climb as soon as it takes off and
the pilot needs to be on pure O2 for 30 odd minutes pre-flight.

Is there a good set of `decompresion tables' for flight?
