Those are PBY's engines close to center and very close together. No expert here, but PBY's had wheels and I suppose could catapult, they took off slow figure a head-wind. Landing on carier?!?! Anyway thanks for sharing.
I drink coffee with a WWII Navy Photographer he shot some the "famous" footage realeased in Time Life Video... hard carrier landing of a ??? that shatters and burst into flames... (not the Midway stuff) he was in the Atlantic. Anyway, he was stunned when he saw his video (footage) in the info-mercial, he said it was on of the scariest moments he ever had, but in the end he said he had the time of his life serving this nation.
