Saw on the news tonight somebody saying the A380 is the biggest aircraft ever. Well actually it's not the biggest ever, it's either the second or third biggest ever, it is however the largest commercial passenger aircraft.

The biggest aircraft in the world is the Antonov An-225 Mriya, pictured below carrying the Soviet space shuttle Buran. Buran is a bit larger than the US space shuttle to give you some scale.
