Hi Jon,

Back in 1958 I was a tech rep for IBM with the 11th Bomb Wing at Altus AFB, OK. One day I was hanging out in the B/N shop when a call

came in that there was trouble on the flight line. One of the aircraft was scheduled for a precise time takeoff for a higher HQ directed mission

and was having B/N problems. If they didn't make their take off time they would lose points for the mission score. SMS Chuck Mattingly,

NCOIC of B/N, and I hopped on a truck and beat it out to the aircraft as fast as we could. When we got there the engines were running and the

wing commander, the bomb squadron commander and the A&E squadron commander were standing there waiting for us. Matt and I climbed

up into the R/N compartment, followed by all three colonels, and looked at the problem.  The lat and long counters in the nav computer ( I'm

talking about the Q-38 now) were running away. Back in those days we used mechanical counters driven by a servo. We quickly isolated the

problem to a cable between the console and a remote rack. Since cable problems are usually located in the connector, we proceeded to install a

breakout box at the remote end and then identified the individual lead in the bundle. Our plan was to take a voltage reading between the remote

connector pin and the middle of the cable. If we had a signal then the problem was at the console end. If we didn't have a signal the problem

was at the remote end. I took the meter lead and stuck it in the breakout box while Matt took his pocket knife with a vary sharp point, clipped

the meter lead to the blade, and carefully pierced the insulation of the conductor. As soon as he did, the two counters snapped into the correct

position and started working properly. We looked at each other, shrugged our shoulders and proceeded to button things up, all the while

keeping our eye on the lat and long counters. We never said a word to each other and climbed down out of the aircraft, followed by the three

colonels. The aircraft proceeded to taxi away and make it's takeoff time and had a successful mission. As Matt and I started to get into the truck

the wing commander called me, "Hey Zellner, get over here!". I told Matt to go ahead and I'd get a ride back. I walked over the colonel and

said, "How in the hell did Sgt. Mattingly know where to stick that knife?". All I could say was, "Well sir, as you know, he's been in this business

for a long time". To this day, I still don't know why the problem went away, but it never reoccurred. I'm sure that all B/N techs have stories to

tell, and this is one of mine.
