Perhaps I misspoke on the dimensions. Being a former airman in the military, I know the C5A Galaxy needs a 7,000 foot runway 7 feet thick. I have not com paired the size of the 777 to the C5A but they are both HUGE as is the A380.

The weight of the plane plus cargo , fuel and passengers is in the 100 ton range.

ps: The C5A weighs in at 400 tons PLUS.

Maximum Takeoff Weight: 840,000 pounds (381,024 kilograms)

Empty operating weights run from 150 to 185 tons.

Max Gross Takeoff Weights run from 270 to 387 tons.

Heavy bird!

BTW, we had a C-5 visit MCAS New River, NC. I assume that it was basically empty, but our longest runway is 5,114ft. I was told the C-5 got off in a little over 3,000 ft.

The C-17 can operate from dirt runways, but of course has much better landing gear. It’s Max GTOW is 292 tons.
