Not ignorance. I’m familiar with the plane. When I reported to Keflavik in January of 1975, Air Operations needed people to park and load/unload planes. I spent a few weeks with torches in my hands, directing the base’s C-117s (slightly longer, up-engined DC-3s) on the tarmac. That’s how I came to see its beak up close: the distinct, angular section of fuselage right above the cockpit windshields. Both the beak and the window frames remain attached to the wreckage. By the way, the plane’s manufacturer, Douglas, no longer exists. It became part of McDonnell Douglas in ‘67. That company merged with Boeing in 1997.
