It has happened to me on a number of occasions in 50 odd years. Best was many moons ago when I was the only pax on an Air Anglia PA-31 Navajo flight from BHX to NWI. As it was a single pilot operation I got to sit in row 0 and was even allowed a go at flying it. Great fun.
I am a bit late I know (been away) but was that not Prospair?
