Are you?
I am not making an argument that the old 747 needs to be replaced, you are.
Well, I happen to be an expert. Five years directly supporting the USAF Airborne Warning and Control System (AWACS) E-3A and E-3B Sentry.
I was assigned to the 552d AWACS Division (Wing) in the Mission Support Deputate, Tinker AFB, OK. I was first assigned tot the Executive Programming Section, then the Software Integration Section. I then worked in the Test and Evaluation Section and became the Chief of the Division Software Integration Section.
Most of my early work was in simulators, but then I deployed to Saudi Arabia several times for operational support. I worked closely with Boeing, Westinghouse and other top contractors doing testing, analysis and certification of radar, communications and computer systems.
I created the magnetic tapes that contained the operating system and utilities for the airborne missions. I received, analyzed, tested and certified changes to the systems provided by many contractors including Boeing. While Boeing was paid to do many of the upgrades, our maintenance personnel did the majority of the hands-on work with contractor oversight. Our program was the only one in the Air Force with zero class 3 mishaps -- meaning there had never been a US AWACS crash .... ever. One NATO AWACS landed in a shallow water landing, but that wasn't a US maintained bird.
The US AWACS were stationed at Tinker AFB, OK, Kadena AB, Okinawa, and Elmendorf AFB, Alaska. We also helped our allies in Europe and Saudi Arabia by selling them E-3 AWACS aircraft and training their flight and mission crews. The US also provided 4 E-3s to Saudi Arabia on a rotation schedule along with crews until they received full delivery of their aircraft. I was fortunate to catch an E-3 rotating back home twice. Much more comfortable than a C-141, plus we got to stay overnight since the trip exceeded the crew duty day. C-141's would land for a couple of hours for fuel and to swap out crews. I spent one night in England, and anohter in Germany.
AWACS aircraft normally perform 16-18 hour missions which the majority is spent flying a race track pattern in a fixed location. Since it carries no defensive weapons or countermeasures, they are usually escorted by fighter jets. Midair refueling by KC-135 and DC-10 tankers extended their capability for mission and transit distances.
We took pride in knowing our jobs and improving them. When I first reported for duty there, the computer process that created the Airborne Operational Computer Program (AOCP) tapes took a month. My boss was able to reduce that time to 7-10 days. When I was given the task, I reduced it further to a single overnight computer job from start to finish. That process used mostly individual tasks that Boeing created. We just added intermediate processes to daisy-chain them one after the other and with intermediate jobs we wrote to verify success of each step before proceeding. This gave us more days for auditing, testing and fixing problems while still delivering a certified tape in less time than before.
Be careful who you complain about being incompetent or "not an expert." That's an opinion with absolutely no experience upon which to base it.
I'm not saying my AWACS experience is the exact same as AF1. I can guarantee you that program is more strictly managed with tighter security though. Being selected to work on these programs means you already have the skills they need. Most are the top of their field, as are many of the contractors. I don't have the same degree of disdain for them as you seem to have.
