another crash

BTW
At least in my glider but I'm sure in just about any; in regards to the headrest blocking vision there is is no frigging way I could even twist my head to see it let alone it blocking my sight.
This unless one has a neck of a giraffe:-)

There's always one in the crowd!

Believe it or not, giraffes can turn their heads no farther than humans, since
both species have the same (7) number of neck vertebrae (or so I seem to
remember reading somewhere, somewhen).

Birds, on the other hand, are reputed to have 13 neck vertebrae, which is
allegedly why (say) owls can turn their heads 180-degrees, whereas we poor
humans and giraffes are limited to 90-degrees. Combine 180-degree range of
motion with birds/owls' quick reflexes, and thus the old wives' tale that you
can kill an owl watching you simply by walking around and around it until it
twists it head off.

Kinda makes you wonder how's come the stories of gliders being able to "sneak
up" on soaring birds in flight! There might BE something to this situational
awareness theory!

We now return to your regularly scheduled programming. You're welcome!

I put that down to birds that regularly soar in flocks (gulls, kites,
vultures) having good, and quite obvious, traffic awareness while
solitary raptors don't. When I've had gulls join my thermal they've
always turned the same way as me but three times now I've had a smallish
hawk (kestrel or similar) come round the thermal the wrong way, suddenly
spot my glider about the same time I saw them, close wings and plummet.
