  • The Tiger gained the dubious distinction of being the first jet aircraft to shoot itself down. On 21 September 1956, during a test-firing of its 20 mm (0.79 in) cannons, pilot Tom Attridge fired two bursts midway through a shallow dive. As the trajectory of the cannon rounds decayed, they ultimately crossed paths with the Tiger as it continued its descent, disabling the aircraft and forcing Attridge to crash-land the aircraft; he survived with a broken leg and multiple broken vertebrae.

    From Wikipedia

    I think just saying that it hit itself due to its high speed doesn‘t really tell the whole story.















  • Digital photo cameras often actually filter out infrared. But even if they wouldn’t it probably would be hard to tell if something is warmer than the surrounding by looking at a photo or video. What you need is a specific device that is calibrated for a specific spectrum of infrared, such as a thermographic camera.

    I think there was actually at least one smartphone that had a thermographic camera installed, but that’s a very specific use case for e.g. construction work.
