Hi guys
I fly them nasty glider things, so I've been in a few fields over the years.
Points to note:-
a) You'll never see the wires themselves until it's too late, it's the poles you may be able to see.
b) From overhead, if the poles are out in the field you may get crop marks around them as a clue
c) If they're embedded in the hedge, especially if there are trees around as well, you may well not see the poles either.
d) If there is a road next to the hedge, the chances are there will be wires as well.
e) That's why not leaving it too late and flying some kind of a circuit round the field to assess slope, surface, stock and obstructions can keep you alive.
f) It's better to climb out of the wreckage at the far end of the field than to be dug out of it at the approach end (no I've not done either!)
g) Hitting wires while still airborne is right out
h) Hitting fence wires on the ground run is right out (if you're in a glider)
So don't plan on just scraping over that nice low hedge, give it 15 feet more (if you can)!
