Which carrier is that?
A practice the USN stopped in 1942. In wartime that practice proved to be too much of a damage control risk when they on top of everything underneath.
From the Wasp Loss in Action Report:
F. stowage of Aircraft in the Overhead
Bays of the Hangar
47. It has been noted in paragraphs 4, 14 and 39 that
the tricing arrangements for four planes triced to the overhead
in the forward portion of the hangar carried away because
of shock and permitted the planes to crash onto other
aircraft parked on the deck. The plane gasoline tanks could
not have escaped damage and gasoline must haye spread into
the hangar. This gasoline was unquestionably the origin
of the fire in the hangar.
48. War experience on other carriers subjected to bombing
attack has demonstrated that fires among triced aircraft
are not only apt to occur but that such fires are very difficult
to control and extinguish because of the overhead location.
Fires among triced aircraft occurred on both ENTERPRISE
and HORNET, and in both cases were difficult to extinguish.
49. The dangers of overhead stowage for planes have been
recognized since the early days of the present war, and on
21 March, 1942 the Secretary of the Navy approved the design
characteristics for the CVB41 class which stated, "reserve
airplane stowage to be provided, if practicable, on the same
level as and adjacent to the ends of the hangar to eliminate
plane s towage overhead".
50. Overhead plane stowage has been omitted on some of
the vessels of the CV9 class because of the strengthening
of the flight deck required to permit operation of the latest
types of heavy planes. strengthening involved the addition
of girders under the flight deck which prohibited the installation
of tricing arrangements. The removal of tricing arrangements
from all other carriers in service or under construction
is now under serious consideration.
