Among them is a tall schooner, an armored speed boat and a submarine berth. In the hanger adjacent to the dock, is moored a large silver airship. The remaining area is taken up by aircraft of all type lined up in neat rows, with taxiways in between them. Many of the airplanes are fitted with pontoons. A ramp between the ship dock and the airship berth leads into the water.
Ponderous doors let out into the Hudson River.
At the rear of the structure the maintenance bays and offices are housed. The overhead is a maze of rolling cranes and steel catwalks. Everything inside the cavernous building is immaculate. In addition to being fortified with concrete and structural steel walls, it possesses a security system that is far ahead of its time.
