Suppose *both* pilots in, say, a B-737, were to die in flight
due to some incredible, but unfortunate coincidence. For
instance, one could die of a heart attack, and the other, say,
of an aneurysm. Now, I'll admit the chances of this happening are
remote, but it could happen; stranger things have.

So, suppose it did happen. If there happened to be an airline pilot
on board who was certified in any of the other Boeing models, from the
717 up the 747 and 777, but having no experience flying the 737, would
he
have much of a problem landing the plane?

Airliners are all very similar. A DC-9 pilot would have no difficulty in
landing a B-777 under reasonable VFR conditions, given 2 miles of a
runway. In the USA it is easy to find big dry salt lakes 5 miles across.
Guess, even a Twin Otter pilot could land a B-777 there if talked to on
radio. A quad-jet may be another matter, but you could always turn off
the outboard engines and land in twin-jet mode just a little bit harder.

Damn it, some planes like the A-320 can fly completely automatically,
take-off, fly, land and roll to the terminal. I guess the pilots are
bored and keep busy by ****ing the stewardesses in-flight. Which
increases the risk of cardiac arrest. Especially if the stewardess is
blone, britney and TOXIC...
