 Aircraft were transported between the hangars and the flight deck by three elevators that took 15 seconds to go from the lower hangar to the flight deck . The forward elevator was larger than the others to allow aircraft that had just landed to be moved below without folding their wings and measured 13 by 16 meters ( 42 ft 8 in × 52 ft 6 in ) . The other elevators were narrower , 13 by 12 meters ( 42 ft 8 in × 39 ft 4 in ) . The ships mounted a crane on the starboard side of the flight deck , abreast the rear elevator . When collapsed , it was flush with the flight deck .
