Live interview on Bryant Gumbel said WING + engine came down first.

A Stinger would likely impact the rear of the engine and
rip off the wing. Remember, there are quite a few
unaccounted for Stingers from the Afgan/USSR conflict.

If I saw pieces of a plane falling off of a flying plane, I could figure out if it was a wing that had fallen off, but I have no idea what an airplane engine looks like. Do you know for sure if the eyewitness who said they saw an engine fall off even knows what an airplane engine looks like? I might see something mechanical that looks like an engine, but that doesn't mean it's an engine. FWIW.
