Now you’re talking! I take it for granted we’re talking about the round-engine Mallard!
Back in the 70s, I had a ride in a BC Airlines Mallard that was doing a round-robin flight - Vancouver to Tofino (land) to Tahsis (water) and Vancouver.
The flight was delayed due to a maintenance issue. We could see a pair of legs in white overalls sticking out of a hatch from the cabin into the tail cone!
Just before departure, the captain comes over to my colleague and me and says:
“You two are the only passengers for Tofino. Because we are so late, would you mind if we went to Tahsis first?“
”Of course not!”
So I got to have the whole amphibious flying-boat experience - landing in the water, taxiing up the ramp, turn around, taxi down the ramp and takeoff. I must dig out and scan my slides.
It was an amazing experience. The water was so calm that it took us more than a mile to unstick!
