I am not following you. Why is visiting Goose Bay relevant? Going over Greenland is usually part of the Great Circle route used between the East Coast in the US and UK/EU but I'm not familiar with Goose Bay.
Another reply in thread explained it. Goose Bay is the United refueling destination when unexpectedly strong headwinds prevent a continuous flight to the US.
Fascinating. I had no idea. I'm surprised they don't use Gander International in Newfoundland. This used to be where nearly all trans-atlantic flights refueled before the arrival of the "jet age." Its a pretty important place still. In fact Gandar is still responsible for all air traffic control over the Western North Atlantic airspace. In fact your plane talks to them until it switches over to Shannon on the West coast of Ireland.
I've heard there's a cocktail lounge there and the pictures on wall of the visitors that passed through Gander are a cultural "who's who" of the 20th century - everyone from the Beatles, to Nehru, Kennedy, Elvis, Castro, Garbo etc, have their pictures on the wall. You basically had to pass through Gander to take a transatlantic flight.
