Slightly off topic but on the subject of dodgy planes.
Was watching an Air Crash Investigation about a Korean cargo plane that went down with 60 seconds of taking off from Stansted airport. It wasn't related to the accident but it was related to giving the site the all clear for the investigators' safety. The 747 series 200 uses depleted plutonium as ballast in the rear tail and tail wings due to its density.
Now isn't that a safe air plane feature to complicate a crash!
