[talk-ph] Flight paths in OSM

[Rally de Leon]

While zoomed in very close, I have mistaken the said flight path for border
or power line lots of times, so I can imagine the headache if there will be
many of these crisscrossing over land data. There's no practical use since
we can't route land-based vehicles to them. Licensed pilots know their way
anyway, as long as we can give them potential emergency landing areas (open
fields & landing strips), as well as give them visual indicators of
potential dangers such as their proximity to high towers, power lines &
mountains peaks (in case of zero visibility & failing instruments). To the
rescue, pilots can reach for their personal gps loaded with osmph. :-)

The ferry routes on the other hand, provides good visual guides of which
ports/ferry terminals are connected, and actually used for vehicle routing
(eg. roro users). Emergency use: in case of boat accidents and you are on a
floating device, you can swim or paddle yourself nearer these ferry routes
for greater chance of  being seen and rescued. I suggest we collect more of
these.
