I’ve often said this to fellow metalheads, but it’s pretty much true: Bruce Dickinson can make anything interesting. Not only is he the air raid siren vocalist for Iron Maiden, but he is also an accomplished solo artist, professional fencer, author (he wrote a kids’ book!), and of course, a qualified pilot.

In fact, for those who haven’t seen the Iron Maiden: Flight 666 documentary, Dickinson actually pilots Ed Force One, a customized 757 that carries the personnel and crew and gear for Iron Maiden when on tour. It’s pretty mind-blowing seeing that stuff all set up in one single plane, watching Dickinson pilot it out into the skies, land it, and then change into his stage gear to scream it out loud on top of the very gear he just flew across the world. Seeing this in action in the Sam Dunn documentary is damn impressive.

Anyway, Dickinson recently recorded a training video called Safety in the Balance for the UK Civil Aviation Authority. The premise of the clip is to discuss the precise requirements in load and balance on aeroplanes, and emphasizes the importance of the mathematical precision to ensure that aircraft, ground staff, crew, and passengers are kept safe.
