<div class="moz-cite-prefix">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.<br>
<br>
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.<br>
<br>
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.<br>
<br>
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.<br>

<div class="gmail_extra">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.<br>

<div class="gmail_extra">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. ;-)<br>
