Can a 747 take off with 2 engines?
Question: If two engines on the same wing of a 747-400 fail, can the jet fly on the other two.
Answer: It depends on the weight and the altitude.
At very heavy weights and high altitude, maintaining altitude on two engines may not be possible.
At lighter weights, it may be possible to maintain altitude with 2 engines..

Why are 777 engines so big?
The reason why: the new engines offer far greater fuel efficiency and much less noise thanks to composite 3D printed materials and larger fan blades. By reducing weight with previously unattainable materials, the engines are able to draw more air, which greatly improves the efficiency and noise part.
