Sikorsky CH-54 Tarhe (N4037S)

Looks like a giant flying insect named Sikorsky

Where are the fuel tanks? It looks to me that they couldn't have much endurance unless the whole aircraft is one big fuel tank!

"Two fuel tanks in fuselage, forward and aft of transmission, each with capacity of 1,664 litres. Total standard fuel capacity 3,328 litres. Provision for auxiliary fuel tank of 1,664 litres capacity, raising total fuel capacity to 4,992 litres."

Originally CH-54 (ARMY), now S64E.

Perfect

So where does it land to pick up its engine? Big hole there.

I saw my first CH-54 in 1969 down at NAS Kingsville, TX where it was sent to retrieve a TF-9J Cougar that had crashed south of the base on the King Ranch. I was impressed when I saw it bring the plane back, drop it off at the squadron, and fly back to Fort Sill (or wherever it came from).

Per serial Number, early CH-54A, more than likely a Vietnam era aircraft. Siller has several of these.

Incrível!
