I'll echo many of the comments on page one. I'll fly quite happily in a bucket seat, tied by a load of string to a couple of sheets of cloth, 6,000ft above the ground, thermal up some cliff in Snowdonia or the Alps and chat to the people on the cliff but stand me on the edge of that cliff and my reaction will vary somewhere between mild discomfort and near panic.
Since falling out of the sky this March, I have felt more nervous when paragliding close to the ground but that's a relative thing - I've always felt safer the higher I am because you have more time to sort it out; plus there's a realisation, having taken maybe ten mins to thermal to cloudbase, that there's not 6,000ft of nothing between you and the ground but 6,000ft of air.
Cheers,
Rich.
