Tests performed by CAB investigators showed that a Stratocruiser that took off with all cowl flaps open would respond very similarly to a Stratocruiser with one engine shut down and could be turned and flown for some time before becoming too unstable to remain in the air.
As probas realizadas polos investigadores da CAB amosaron que un Stratocruiser que engalase coas solapas de capucha abertas respostaría de xeito semellante a un Stratocruiser cun motor apagado e podería xirarse e voar durante un tempo antes de facerse demasiado inestable como para seguir no aire.
