Aut cum scuto aut in scuto
Airbus translated from the French: may or may not get off the ground. if not, it may or may not stop in time. if it does get off the ground, when it returns to the ground-and it assuredly will-it may or may not return as a unified bit of kit. In one of the more brilliant bit of engineering Airbus has done over several aircraft is to put the lavatories right over the spaces reserved for flight critical electronics and navigation black boxes. should "leakage" occur, the results have been very sad.
