A group of us worked at General Electric and back in 1980 all 8 of us had a modification to comply with on the fuel system on the CF6-5OE2, we were under guard and worked under the two man policy we completed our job in three days 16 hrs each group because we could not ground the E4 we were later given a tour and if the people know what such an good looking aircraft it was and at the time it had capsule inside with fridge type doors it was amazing we also did the support for Air Force One on the CF6-80C2 Engines the need of those E4's is very important to our nation.

My older brother was the XO for the Doomsday Plane in the early years, out of Offut in Omaha. He took my wife and I on a 'cooks tour" of the oldest one of the 4s. It was amazing, the offices, meeting rooms and living spaces (President and Joint Chiefs rode it.) one deck, monitoring stations for all the comm equipment on another deck, and a complete repair facility for anything aboard (maybe a pacemaker excluded...I don't know) on another deck. It is amazing that an aircraft that weighs somewhat the same as a UP Big Boy locomotive would fly, and fly well. Nightwatch and Looking Glass are corelated very valuable missions to protect our freedom and our continued government.

I was an inflight Maintenance technician on the E4-B from 91-94 after being transfered from Ellsworth AFB. After flying and working on almost every model of the EC-135, the E4-B was like a dream. I have too many fond memories and stories of my Air Force career (that my children have heard numerous times). I have pictures of the E4-B that were given to me upon departure from offutt that still hang in my home office ( with other cold war memorabilia) that I truly treasure.

I used to be neighbors with Harry Fogarty when he lived in Greensboro. I think he was a good aircraft mechanic. He used to say "if it has a screw....turn it"

My father worked on the E4 program from day one until yesterday. He retired from the military in 1984 and then went to work for Boeing on the E4 program. He has worked on this plain for about 36 years.

At his retirement ceremony yesterday, an E4 flew to Tinker AFB with an American flag on it. They then flew the flag in his honor and retrieved it and handed it to him.

Thanks to those who have been involved in this program and to those who were responsible for doing this for him. It was a very special moment for him.

Over the years that the Air Force had operational E-4 aircraft, little has been puplished about the aircraft and few people, even Air Force personnel, were aware of the aircraft or the mission. The primary body of the E-4 was that of a 747 airceaft. Prior to being assigned to Offutt AFB NE the E-4 aircraft were assigned to Andrews AFB. At that time I was the Tech Advisor for the DCM at Offutt AFB. A team of Air Force personnel from Offutt AFB were sent to Andrews to conduct an ORI on the E-4 Operation. As the senior CMS (E9) with the group I was the enlisted team chief for the ORI Team. After the ORI was completed, several of the ORI Team members were flown back to Offutt on one of the E-4 Aircraft. I was very impressed with what I was allowed to see on the flght. Soon after we returned to Offutt AFB, we were informed that the E-4 operation was going to be moved to Offutt AFB. The primary mission for the E-4 at that time was as an Airborn Command Post in case of war. The secondary mission was the survival of the President of the USA and as such, one of the aircraft was flown to Andrews AFB when ever the President was in DC and when he left DC, one of the aircraft had to be flown to a location within 15 minutes of where the President went. The Air Force refered to these mission as AABNCP and NEACP Missions.

At the time the E-4 Aircrft was moved to Offutt AFB, the Air Force had only four of the specially build 747 aircraft, which the Air Force called the E-4 Aircraft. To perform the assigned missions, the aircraft require a large number of very expensive black boxes. Even with the importance of the missions, only enough money was approved to purchase three sets of black boxes. Therefore, a utilization schedule had to be drafted to move black boxes from aircraft to aircraft when an aircraft needed to be taken out of service for maintenance. I was personally request by Hq Sac to perform this task.
