Well I'm a professional pilot and a new diver.

I always try to leave at least 24 hours between dive and fly. I fly on a
business jet, so the cabin is lower than on a airliner, even if we fly
higher, but you have to consider the possibility of a loss of
pressurization, you might find yourself at 30000 ft in few minutes.

Since the bends could be catastrophic to not only you but others, you
are wise to be very conservative even if you lose some diving. You
might want to find someone knowledgeable to give you specific advice for
your situation.

If you fly a biz jet you might find yerself a lot worse off than
30000ft.....and it could take a few seconds, not minutes.

You would really have to lose the cabin door to loose pressurization in
few seconds.
For a window or 2 it will take a moment and then you would already be in
an emergency descent.
It should take 3 minutes for a descent from 45000' down to 10000', so
you should meet the cabin in the thirties.

If you don't have a medical problem in the mean time. I would call DAN
(Divers Alert Network) and ask them what their recommendations are for a
professional pilot who will be at the controls. As divers, what we do
is poorly documented, but you're getting way out beyond what even
technical divers do. How many dives do you do? How deep? Are you
doing Nitrox? If not, you ought to seriously look into it.

As a non-medical doctor, I leave it to you to calculate how many
atmospheres light you are at 30,000 feet and guess what this might do to
your cardiovascular system if there is any nitrogen in your blood. My
rough guess is that it would make your circulatory system pump something
like the head on a beer.

Look at this another way. With just a short dive, would you want to get
shot to 30,000 feet? Not even the Navy divers try anything like this.

Do you have pressurized oxygen available?

Is there another pilot to assist you?

What's the difference between "a moment" and a few seconds? What is your
'time of useful consciousness' at 45,000ft? Why , if one crewmember leaves
his or her position, is the other required to wear their oxygen mask above
350?
Do you know what 'explosive decompression' means?
Do you think losing the window at 450 wouldn't be considered an explosive
decompression?
Enquiring minds and all. ;)

I'd imagine you're pretty close.

No, (*) and yes.
But I'll be interested in gabrielles answers too. ;)
Note the (*), O2 is usually delivered at a working pressure between 60-80psi
to the mask, which is *relatively* high considering the outside conditions,
though not by diving standards.

Good combination. Fly us somewhere.

It wasn't all that long ago that a crew found themselves in a similar
situation . . . well, they didn't exactly find themselves. The crash
investigators found them (as I recall). Turns out it was a combination of a
slow leak and a malfunctioning alarm. They just went to sleep, never to
awaken.

Heh Heh true enough, but I'm sure his engines burn $$$$ just like they all
do.

Yea I think they had a famous golf pro on board. Started out in FL and just
flew off course until they crashed somewhere out West. Just shows to go
ya...you never know like you think you know what's going to happen today.
That's why I'm going through my Rescue class. Just to tilt the odds ever so
slightly towards I or those with me on my next dive not getting dead or any
injuries minimized.
