Silvaire1,
That's interesting. I had always assumed it was purely a UK usage. I've been in Canada for a long time and I don't think I've ever heard it here.
Slight thread drift, but I've always thought the Silvaire is such an elegant aircraft.
It's hard to believe it dates back to 1937. In Britain, most new private aircraft were still biplanes!
It would be very rude to call a Silvaire a Spam Can!
