With wing mounted engines on two-engine airliners, there is physically no way to take off on one from other than a dry lake bed. The thrust from the operating engine will introduce more yaw on the airplane than the rudder, nosewheel steering, and wheel brakes can counteract.
Even tail mounted engines (with a shorter coupling arm to the centerline) will typically have a Vmcg (roughly, speed at which lateral control on the ground is lost with one engine inoperative) that will preclude takeoff on one (physically, not by regulations) from available runways.
Really? You know of examples of passenger planes taking off with only one engine turning? Or of any twin engine airplane doing this deliberately (other than a test flight or desperate emergency, like the volcano is gonna blow any moment).
i was lalking about the situation of planes taking off in barely flyable/safe situations that would not be allowed by modern faa regulations, which it think is larger point that was being argued, not debating about the single engine or propeller case
