Maybe this test flight would have been a more realistic simulation if, on shutting down No 2, they had then cut the engine restart circuitry with the pliers!
You have a very valid point there, WHBM. As what cargo boy had said, the scenario is entirely different if you know you have got nothing to bank on in a real life scenario crossing the pond with 3-5hours to go for the next landing strip, not my idea of over water flight. Guess I'm just too spoilt with 4 engines..
