How much does a jet plane weigh?

That's a tough question to answer as there are so many different types of jet aircraft (experimental, military, business, commercial passenger, commercial freighter, etc.), and also many different ways to categorize weight. The lightest empty weight (no fuel or payload) for a jet aircraft is the BD-5 at just 358 lbs. Normally, though, an aircraft is classified according to its Maximum Take Off Gross Weight (MTOGW) and the heaviest is the Russian AN-225 with a MTOGW of nearly 1.3 million lbs., followed by the new Airbus A380 at just over 1.2 million lbs.
