Easily. My MU-2 can descend 10,000fpm. Any jet can easily do it.

Basically, the pilots need to get their masks on and get the plane down

a little more leisurely, but not much - there's always someone in the

section who panicked and isn't wearing a mask.

One aspect that I have not seen addressed in this thread is the fact
that most oxygen systems can provide supplemental oxygen for a few
minutes only (I dimly recall figures like 3-5 minutes, but that may be
inaccurate). The pilots also need to get down to 10,000 feet within
that time before everyone's oxygen generators run out.

How could an SST like the Concorde get from cruising altitude down to
10,000 feet in 3-5 minutes?
