THERE IS AN ALTERNATIVE TO DECOMPRESSION DISASTER

OXYGEN
it has to be set up in advance. WAY IN ADVANCE

while preflighting, hook up the OX mask and TEST IT; leave it dangling and
in the event of decompression, you have the life saving connection, ten seconds away

NOT ENOUGH
to know where the mask is located; not enough to know how to turn it on,
   in the event of a decompression you are going to be quite busy troubleshooting and
      flying the plane

FLIGHT LEVELS
    Oxygen would have save two lives in a TBM

OR 6,000 feet per minute right now

FOR EXAMPLE
Payne Stewart died in a Lear Jet.

the plane required two pilots and one of them had to be wearing Oxygen
at all times when at 39,000 feet. if they had, they would all likely still be alive


i) At least one pilot at the controls shall wear, secured and sealed,
an oxygen mask that either supplies oxygen at all times or automatically
supplies oxygen whenever the cabin pressure altitude exceeds 12,000 feet
MSL; and
