The main difference between Trump and Reagan is Trump wants to immediately take the plane while still president. Reagan did not take Airforce one when he was in office. It was also not a gift from a foreign government either. In fact, the Reagan library knew the 707 former airforce one was being retired and fought to get it in 2000/2001. They got the donation in 2001 for a static display. That is 12 years after Reagan left office.
Trump made a deal to get the airplane and have it automatically donated to his library in 2029 before he leaves office. The real question is what is his plan to be able to personally use it after it is donated to his library. No one knows what his real plan is at this point. Everyone doubts it will be just gutted and put on static display.
There is no way for this qatar aircraft to be securely used as airforce one. It will take a few years to strip it down and rebuild for security. But… since trump does not care about security, he will force the secret service and DOD to let him use it anyways. Congress will not stop him. It wont matter that using this aircraft will break all security standards.
Boeing now says the new Airforce One will be delivered in 2027, 3 years late from original contract for 2024 (original contract time was from 2018 to 2024).
The ironic part of for the reason of the Boeing delays was they converted 2 passenger 747s from canceled orders and they basically admitted it would have been faster to build a new aircraft from scratch. But they also had the same supply chain issues everyone else had during covid.
This qatar situation is just another mess of corruption. Trump seems to be pissing off the entire world except middle eastern countries and russia.
Now if he wanted the existing airforce one to go to his library as a static display, after it is retired, then most would not care. Some would complain. But it at least would not have been corrupt.
In the end, congress has made it clear they will let Trump do whatever he wants.
