A tad of authenticity seems to go along with this tall tale, which may be why people are so quick to believe it. While to date no one has been killed (except in various television shows, movies, and other pop culture references) it IS possible to be hit by a chunk of ice falling from an airplane. Even MythBusters said that part was true! But, does that mean this photo is proof of such? Of course not...and all it took was a 3-minute Google search.
This image comes from a satirical news story featured on the comedic (and completely made up) news broadcast, The Day Today. Airing in 1994, The Day Today is a series of six half-hour episodes full of utter hilarity. Hosted by Chris Morris, the show has long been off the air, originally being shown on BBC2, but all six episodes can be found on Youtube! In fact, if you'd like to see this story as it aired, you can find it in Episode One, about 23 minutes and 24 seconds into the 'broadcast!'
