Boeing 747-400: The Mega-Top (Osprey Civil Aircraft)

Currently the world's heaviest and most powerful airliner, the 747-400 features a state-of-the-art Electronic Flight Instrumentation System (EFIS)that renders the flight engineer's position obsolete, while engine options from Rolls-Royce, Pratt & Whitney, and General Electric permit take-off weights of up to 875,000 pounds. Despite a price tag of around $95 million each, the 400 has been an overwhelming success with global operators -- more than 45 airlines around the world have 400s in service or on order.
