The An-225 Mriya
This Antonov vessel was made in the Ukrainian SSR back in the ‘80s. According to CNN, the An-225 Mriya is still considered the “undisputed superstar of the skies”! It is basically a cruise ship on air. It has a 640-ton takeoff weight. In 2016, it went on a rare flight to bring a 130-ton generator to Australia.
The Convair XC-99
This is one more monster plane that is considered a pioneer. The Convair XC-99 is only bested by Hercules as the largest piston engine-powered aircraft in history. It has a wingspan measuring 230 feet and six rear-mounted turbines. Clearly, it is a force to be reckoned with! During one mission, it delivered cargo weighing 40,000 tons. It was retired in 1957 and now resides in Ohio.
