In this first video (dated on 19/April/2014) we can watch the MSN3 prototype taking off in Toulouse with the MTOW (Maximum Take Off Weight) take off with a single engine, once the other engine is cut during the acceleration. After achieving the Vr, the aircraft lift off and clears a hypothetical 35ft obstacle at V2. Once the aircraft reaches the minimum climb gradient of 2,4%, the second engine is re-lighted.

Notice that the right engine is off .
Notice the Rudder position during the take off
The smoke from the right engine is produced when this second engine is re-started.
This test is the typical failure mode performed in simulator sessions by all line pilots during the standard training.
In this second video (dated on 11/January/2014) we can heard the impressive “bang” produced when the engine is cut during the acceleration phase.
