So this is personal to me. My grandpa owned a 1967 M20F, tail N2996L. Right after Christmas 2003, his mechanic/friend borrowed the plane to fly up to Ohio to visit family. He departed Ohio to come back to Florida but never made it. The plane crashed at the SC/NC border, with his friend perishing in the crash. Now it just so happens I'm working in the area, and if I can get a day off I'd like to go visit the crash site. I haven't seen the plane since I was a kid and I feel like it would bring some closure (wreckage is long gone). But something I can't workout:
The NTSB narrative says he ran out of fuel. Both tanks were dry, nothing in the fuel spider, and no browning of vegetation and no post-impact fire. Yet the son of the PIC states the aircraft topped off with fuel from departure. The route (best I can figure out) was OH29-24J, which is 646nm. My little M20D with puny 48 gallon tanks could make that (in a no-wind scenario) with daytime VFR reserves. How does a turbo-normalized M20F with 64 gallons not make that? Not only that, the crash site is only 345nm from departure. Possibly ran one tank dry and couldn't switch? Departure time 10:15, crashed ~12:30. That time and distance works out to an average speed of 153 knots across the ground
Assuming he was on one tank the entire time from takeoff,cruise, and finally starvation means he burned 32 gallons in 135 minutes which works out to be 14gph. That sounds plausible. But why would the other tank be dry?
Whats even MORE perplexing is there was a small (but suitable) airport a few miles away to his southwest along his route, but witnesses at the crash site say they saw him flying NORTH, which was away from the nearest suitable airport. I remember for a fact the aircraft was fitted with one of the early yoke-mount B&W moving map Garmin GPS units.
FWIW, the PIC was a commercial single/multi-engine pilot with over 3,500 hours and an A&P/IA cert. Aircraft did not have shoulder harnesses. It did have a working wing-leveler.
