Balloon plus...

I was going to blip my work today of paper clearing resulting in 7 sacks of past work papers, reports and valuations from the late 1990's to 2002 when I had to give up my business but this evening I saw this balloon being buzzed by 4 hang gliders (but they would not all appear at the same time) so there are only 2.
I do wonder what the balloon pilot thought of them but it was too far away to hear any abuse being hurled!
