B-47 Bomb Nav maintenance by: Bud DeHaan


Just thought of something that happened to me when I was working on B-47's @ Lincoln AFB as a member of the 98th A&E Squadron in 1963.

I was working with another airman and we had changed a Stab Unit on one of our aircraft. The Stab unit was located at the foot of the navigators seat in the nose of the aircraft, under the periscope. After the swap out, we were boresighting the stab unit to align the radar to the periscope. It was a hot summer day and must have been over 100 degrees in the plane so the sweat was pouring off. Ground air conditioning was for aircrew preflights!

We had the top cover off of the Stab Unit and I am sitting on the floor with my arms and legs wrapped around the unit, leaning forward to reach a syncro on the back side of the unit. The other airman was sitting in the seat watching the radar till I had it adjusted to the correct azimuth, so I could tighten down the synchro.

While tightening one of the three screws that held the syncro down, I touched my chin to 600vdc. (I believe it was called the Theta Motor) The sudden shock caused a spasm in my neck, jerking my head back, hitting the periscope. Like a basketball, my head bounced back down into the stab unit. I made about three round trips before the airman could grab my collar and pull me back from the stab unit.

The only injury sustained were a large lump on the back of my head, several small lacerations on the chin from the power strip and one rather large headache. I was sent home for the rest of the day.

I guess looking back, they would have to be fond memories.
