Is the Russian Antanov aircraft still the worlds biggest aircraft.?

Yes. The The Antonov An-225 Mriya is the largest operational aircraft in the world, it's 3 engines are more powerful than that of Concorde, it can lift about 600,000 kg of freight. It has a total of 32 wheels, and it is operated by Antanov industries and also by Foyle Airlines who pay for the maintaince. It is well maintained as it commissioned frequently to fly freight misson and also has carried a russian space shuttle

Yes I've seen a comparasen between a few aircraft the last two were the a380 and the an-225 the a380 is not far behind but yes the an-225 is still a bit bigger

Hope that helps

The Spruce Goose is the worlds biggest aircraft.

If you are refering to the world's biggest FLYING aircraft, it is. However, If you are refering to the world's biggest aircraft, no. The world's biggest aircraft is the Spruce Goose.
