Helicopters do sort of potter about though. Like the one that crashed onto a pub in Glasgow last decade.
I think it was in the 1980s that a photo snooper caught The Sensational She-Hulk, who had temporarily joined the Fantastic Four, sunbathing on the roof of their famous New York skyscraper. When the FF (I think the Human Torch specifically, he can fly) looked for the culprit, there were dozens of helicopters. Dang.
(To be clear, this was in a comic. #275 actually.)
The pictures were published without her permission, alas. But, being a Hulk, she's green, but the printer assumed that the pictures weren't, so corrected the colour. Result, anonymity.
