Back to Gander:
About 30-40 years ago, there was a superb collection of photos on a mezzanine floor in the terminal, of aircraft that had passed through, with particular emphasis on the 1930s. The abiding theme was "He departed Gander on (insert date) bound for (insert European destination) and was never seen again...…………………….."
Perhaps too ominous for nervous passengers about to cross the Atlantic. The last time I stopped there, about 1991, the terminal had recently been redeveloped and the photos had gone. I do hope they have been preserved somewhere appropriate.
