Ntoriuosly, senators and planes never seem to end well. Stevens, Obenshain, etc.
Heinz (helo), Wellstone also come to mind.
What strikes me is that driving for 45 years I can only recall engine failure three times, but the number of hours on the road way excedes what I would experience casually in the air. Plus, not nearly the attention to maintenance. Two of the times were due to rubber belt failures which in a plane would have been proactively replaced. The third time, was due to an electrical fuse problem but the manufacturer (Chevrolet) already had a bulletin out.
Piston planes are dangerous.
Small planes always grab a fair share of deaths in any group that uses them frequently -
