"On 15 February, the group discovered how unsuited its Airacobras
were for combat. Roy Spencer and William Melton of the 302nd FS
spotted a Ju 88 flying a reconnaissance mission near Ponsa Point,
at the mouth of Naples Harbour. Both men succeeding in damaging
the German aircraft, yet the Ju 88 was still able to both climb and
accelerate away from its frustrated pursuers."
