Newfoundland is the first place I visited outside the US when the DC-6 in which I was flying to Germany landed at the airport in Gander to refuel in 1961. This was a popular refueling spot for transatlantic flights in those days.
I would guess the airports at St. John’s and at Gander get more traffic than the one in Stephenville. A plane crash on Dec. 12, 1985, near the Gander airport killed 256 people, most of them US servicemen returning from peacekeeping duties in the Middle East. There’s now a memorial to the dead at the site of the crash which I saw in 1997.
