A trivial one after all the others here. I had signed up for a paragliding course in the south of France, but the weather hadn't worked out. In compensation the owner of the school said he would take us up a local peak, and we would do a buddy jump. We should be in the air for five to ten minutes.
A long drive on dirt roads up through state forestry, and eventually, we get to the peak, and launch. I'm just a passenger, but we are about 2000ft over the valley floor, when two military jets went past below us.
