Just a note in passing, us paraglider & hanglider pilots (meat missiles?) are very capable nowadays of flying in excess of 100 miles in thermic conditions. Indeed, one of our local lads bagged Brighton to Deal last week south of the London FIR, that's 126kms on an ENE bearing.
We're hard to see and for some reason, gliding sites have been removed from airmaps. Airprox incidents are unsurprisingly getting more common as a result. We fly always on VFR (obviously) and operate see & be seen as a principle.
As always, a few idiots amongst us will wander across atz's from time to time, but by & large, we're a nice sensible bunch not wanting to upset anyone. So in the absence of marked maps, please knock in a quick heads up ifd you happen to be near hills and at cloudbase or below on a sunny light wind day!
