The accident airplane is both described & depicted as having crashed, directly, into an airport hangar, but Flight 191 initially crashed into a field (an interviewee states this right after the above) adjacent to a large trailer park (which did sustain some damage in the process) & subsequently destroyed the storage hangar; this sequence was related, both in footage & by the narrator ("also," referring to the hangar), about 1 minute afterward.
The 2 casualties on the ground are described as "working in the (storage) hangar" that the wreckage impacted, but they actually were employees of a nearby repair yard.
