I wish my friend Brian P Quinn had had a parachute on November 6. The PT-6 in his Cessna 208 seized, spewing oil over his windshield. Despite this, he put his aircraft on the ground just fine, but landed long, and hit a tree that he surely couldn't see.
Would he have used a chute, had it been available? I don't know, but I do know had he used a chute, he'd probably be alive today.
If I was single-engine out in zero visibility, I think I’d pull the handle.
