They are extremely remarkable. We've come a long way since Oville and
Wilbur and Otto. 

A restart is always worth a try after a compressor stall. One tends to
be very wary, though, feeling for vibrations that might indicate an
OOB condition caused by a busted bucket, watching the engine temp and
turns gauges, and in general flying with whiskers bristling out in all
directions. I don't know a pilot who would take an aircraft anywhere he
didn't absolutely have to take it after a compressor stall.
