You are correct Ted. Here is the original on our website with narrative by Don Thompson:
Sealord 6 - BuNo 15785603/22/1971, Aircraft Minor Damage, No Injuries. Assigned 1/22/70.
Crashed on takeoff at Binh Thuy, no casualties 8/13/70.
(Don Thompson wrote: About my 3rd day at HAL-3, I heard a racket in my room in the barracks, opened the door and saw a helicopter blade sticking out of my barracks building. I ran towards the flight line to find a Sealords aircraft lying on it's side. There were no injuries but the aircraft was trashed. That was 157856 which was apparently rebuilt as my log book shows that I flew it in July 13, 1971.)
Rescued 4 personnel from CH-46 downed by enemy action 11/25/1971.
Ref: Joe Baugher showed civil registry as N157LC. (Your link shows a change in Registration#)
8/31/16 Howard Jacobs mentioned hearing during Savannah Reunion, that SL-6 was looking for a home.
