High-lift devices compensate for this design trade-off by adding lift at takeoff and landing, reducing the speed and distance required to safely land the aircraft, and allowing the use of a more efficient wing in flight. The high-lift devices on the Boeing 747-400, for example, increase the wing area by 21% and increase the lift generated by 90 ...

The aircraft was planned to fly towards the target at 400–440 mph (640–710 km/h) and deliver their weapons from 400 ft (120 m) or lower.
