Believe it or not I actually flew that 72 (years after the incident). That thing was terrible to fly. It was impossible to keep it in trim.
Two things saved them.
1. The 72 is one hell of a well-built airplane.
2. They threw the gear out at about 400kts +.
I don’t know if it is still flying or not, the last I heard it been converted in to a cargo airplane and Express One out of Dallas was operating it.
