largest planes ever
An-225, largest plane in the world. The An-225 is quoted as having a maximum takeoff weight of over 1.3 million pounds (600,000 kg). The FAI gives credit for a slightly lower weight of 1.12 million pounds (508,200 kg), the record set by an An-225 in 1989 for the largest mass ever lifted by an airplane to an altitude of 6,500 ft (2,000 m).
