+1 on the glidability of commercial aircraft. I can remember two incidents (besides the one into the Hudson) without looking them up.

There was the Air Canada aircraft that ran out of fuel (fueling error when metric replaced gallons) at cruising altitude, and ended up doing a glider landing at an unused air force base, where a bunch of people were all watching drag races with their backs to the silent aircraft. One kid turned his head in time to clear the runway.

The other was a China Air flight that was coming into (I think) San Jose, CA. The last I heard, the fuel lines had frozen. They were a glider for the ten minutes it took for the lower altitude and warmer temps to thaw the lines so the crew could get the engines started again. IIRC, when they got the engines restarted they were only 1500' off the ground.

Both of these were in the 80s.
