I'm wondering what the most powerful airplane is, and I think it is the A380F.
With it's 4 engines at 77.000 lb (GE7277) of thrust, I will have a total thrust of 308.000 lb!
The An-225 has 6 engines of 50.000 lb right? So it's total thrust is 300.000 lb, a bit less than the A380F.
So, is the 380F the most powerful airplane ever built/going to be built?
(Probably soon to be surpassed by the A380-900 though, which should have something around 4*80.000 lb)
