A hot air balloon

This shows a hot air balloon being prepared for a flight. It looks, by the amount the balloon is inflated, that it is almost ready to take off and the people around the basket are perhaps just about to jump in. The date on the slide mount is April 1980, which was of course the processing date, so this could have been taken in any season really, but the sky looks like it is the perfect day for being up in a balloon.
