     Between 0945 and 1020 six definite explosions were reported in the hangar. Explosions at 0945 and 1006 were described as minor while those at 1002, 1003 and 1005 were classed as major explosions and the explosion at 1020 was described as a heavy explosion but less severe than some previous ones. The cause of these explosions was not reported and can only be estimated from the damage sustained by the ship and the known condition of loading. Each of the six torpedo planes spotted in the hangar was armed with one Mark 13, torpex-loaded torpedo and was fully gassed, including auxiliary wing tanks. Explosions in the hangar therefore might have been either detonations of torpedoes or gasoline vapor explosions.
