From my modest RPAS pilot experience, I can tell that during a flight
planning, while using different sources: maps, satellite images, GPS
traces, Wikimedia images, videos, etc. I kind of inadvertently build in
my head a 3D model of an area, paying attention to distinctive
landmarks, and especially to a point of landing.
In this particular case, I could map the control tower also only after I
saw videos, aerial and ground photos, satellite images of the
Haßfurt-Schweinfurt airport. After the tower, a major landmark, is on
the map, here it is, I have got the 3D model.
Human brain works in 2D, that is why it takes years and years to train a
good pilot. The professional term for a flight is: jump. Aircraft does
not fly like a bird, it has got limitations of a jump (END - endurance,
EET - estimated elapse time, ALT - alternate aerodrome, flight plan,
etc.). A pilot error is not always caused by high spirits or illness,
sometimes it is a result of objective limitations of human physiology.
That is why any flight has got a flight planning phase.
By the way, if a smartphone battery has drained, if "Find My Phone"
can’t locate the device, the last known location is displayed on a map.

agreed, I would also believe that the military _also_ might look at
OSM (every additional source is always useful), but very likely not
for flying aircraft, still, I don't believe there is any correlation
whatsoever between a military helicopter touching an airport control
tower at daytime and good weather conditions, and this tower mapped in
OSM or not. And even if it would have been a thunderstorm and foggy
and night time, there wouldn't be any correlation between the accident
and OSM (besides that you became aware of the tower and mapped it
because of the news). Usually accidents like this happen because of
high spirits or someone having an heart attack or similar.
On a sidenote, I think you overestimate the technology to find your
smartphone, you would very likely not find it in the ocean or in a
river or lake, or in a cave, or after some hours when the battery has
drained, or in an area without cellphone or wireless reception, or if
it was inside a shielding containment, etc. ;-)
