Actually, I worked for a Shell Aero Center ‘years’ ago, and ran my 340 Cuda on Avgas for free for 3 years!!! Thanks Shell . . .
We also had afew late night parties in the Shell International Gulfstream II G-BSAL.
My best Shell Canada story, at the time Shell was based in our hangar in Toronto. They flew the CEO of Shell out to Edmonton. The flight Crew and the CEO were all staying in the same hotel.
They had an early morning departure back to Toronto, and both crew were drinking into the late hours in a local bar. When they got back to the hotel, they were sneaking up the stairs to their room, instead of the public elevators.
On the way up the stairs, they ran into the Shell CEO sneaking down the stairs with a hooker!!
It was a very quite ride home . . .
My local FBO; Millionaire YKZ has BP. I don’t know about today, but all the Shell Aviation fuel in Canada, actually came from BP.
