"...desperate attempt to reach Le Bourget only option...."
No! The only option under the circumstances was to have crash landed on the highway or in a farmer's field. It should have been an instinctive survival decision. A decision reguiring neither time nor thought. A decision based soley on the Airspeed, which was decreasing. Three times the F/O had warned Marty about decreasing airspeed.
Regardless of an impossible situation, never for one second give up the struggle to stay alive. Marty did not possess the ultimate survival instinct.
It's a classic scenario of controlled crash vs. stall and assured death.
