People love to watch airplanes. That’s why airshows are one of the world’s most popular spectator events. Aviation enthusiasts will risk sunburn and dehydration to stand at an airport, sunglassed eyes scanning the skies, to watch pilots demonstrate their planes’ performance. Fast-moving and incredibly noisy military jets will make them reach down to cover their kids’ ears, and they’ll haul kilos of photo gear around to “get the shot.”
