A friend at the dayjob today claimed that when he was on holiday in Florida he could look out over the sea and see Cuba.That's about eighty miles isn't it? Wouldn't the curvature of the earth prevent that? Floridians please comment. I think the furthest distance I've ever seen was from Victoria on Vancouver Island to a snow-capped mountain range in the States and back home in the UK i've certainly looked over to France from the south coast and Ireland from the west but that's less than 30 miles in each case. So here's todays puzzler - what is the longest line of sight you have experienced? Where and when? Only when your feet were on the ground and with the naked eye please not from a balloon or while wing-walking on a 747.
