The fuel receipt showed they got 53.x gallons of 100LL fuel. I realize it’s just paper, but a ‘mis fuel’ seems a lower likelihood. I also think with the two attuned pilots around during this shorter fuel stop, any Jet fuel truck or hose would of been noticed.
I believe the report stated that there was a smell of 100LL at the crash site as well. Agreed that misfueling seems improbable based on current evidence.
Looks like one is KTAS vs KIAS, true vs indicated. I believe several aircraft can get their KTAS up close to their Vne KIAS or beyond. The Mooney Acclaim Ultra is one such plane, with a KTAS max cruise of 242 knots (allegedly) but a Vne KIAS of something like 195 or 196.. I want to say the Cirrus will also push its max cruise KTAS up to or past the KIAS Vne
