Hitting the runway on a go-around is not the greatest airmanship, but the Aerostar pilot did one thing right: he didn’t panic and continued flying the airplane.
Aerostar with curled props after ground contact.
It is interesting to see that a plane can fly 80 miles with both prop tips curled back 6″, but then it was a light load.
Most pilots would argue that he should have returned for landing despite not having on-airport repair facilities, but crating the plane up and shipping it back home becomes a pressing factor when you’re the owner.
(When I did my commercial training in Florida, the owner specifically requested that instructors and renters return home for repairs instead of landing at nearby Cape Canaveral, which had a much longer runway. We ignored him, as a matter of safety, of course, but we weren’t paying for potential crating/shipping of broken airplanes.)
“Q-tip” prop design increases efficiency with less span-wise airflow (“air fence”) and reduces noise (smaller blade diameter means lower tip velocity, which approaches speed of sound.) It also increases ground clearance.
