I spent several years in a job that required me to frequently be on a lake and frequently involved the use of a boat. As a part of that job, I went to trade shows for boats and boating tools and accessories. A frequently stated factoid was that one could expect to spend between 10% - 20% of the retail cost of the boat every year for fuel, maintenance, storage, repair and incidentals. Funny thing, since that cost was estimated based on the retail cost of the boat, the yearly cost did not go down if you got a really good deal on the boat. Even if the boat was free, you could expect to spend 10% - 20% of the retail cost of the boat every year for the non-fun stuff that had to get done.
A while back a friend gave me a Groupon for a meal at a new(ish), high end restaurant. To this day, that free meal remains one of my more expensive visits to a restaurant. There was a lovely jazz band playing and everything except the entree was an extra cost. If I had needed transportation, taxi or Uber, it would probably be the most expensive meal. I lived within walking distance so that didn't happen but even without the extra expense, it hurt.
I have received other "gifts" that cost me a lot of money or a lot of time to fix or both. I could go on with a exhaustive list of seriously expensive "free stuff" but you probably understand already. As a general rule, it has been my experience that the greater the value of the gift I am given, the more it has cost me. I have no reason to believe that my experiences are unique or even rare. I have certainly observed a very similar set of circumstances for friends, family and even strangers.
So, to get to the point, Felon47 is being offered a "gift" of a Boeing 747 from the kingdom of Qatar. I suppose technically it would be a "gift" to the USA but the Felon has already expressed a desire to use it as Air Force One (whatever plane under Air Force command that the POTUS is flying in) and then transfer it to the Felon47 coloring book repository (library) once he is out of office for his continued use. A plan structured so as to hang the costs of maintaining and operating the airplane on the American taxpayer while the Felon has exclusive use of it.
We could talk about security concerns if we wanted to have a book length discussion but for some reason, that does not seem to be a concern for the Felon or his merry band of incompetents. So I will only mention the Felon's highest priority - money. Suffice to say that the current planes with the modifications for communications, medical, security, ECM, in flight refueling etc etc costs $3-$5billion a piece. (Personally, I say leave all that stuff off and let the Felon fly around in a vulnerable palace but TBF, I absolutely do not care what happens to the 1st asswipe.)
I have never owned an airplane. I have no real idea of the ownership costs of a low end Cessna much less a customized 747. However, I would bet dollars to donuts that it is not less than a recreational boat. So let's use that 20% estimate. Even though the two current AF1 planes are perfectly operational, we are talking about spending an additional $80million a year for this "gift". Of course, the Felon has business, political and personal enemies so to the regular cost, we will have to add enhanced security to a level acceptable by the Secret Service. That will mean a minimum of several 24/7 security guards. I think we can safely round up the cost of that "gift" to at least $100million a year. That is not the cost to operate the bird, those costs already exist for the current planes. The $100million a year is simply an incredibly conservative guesstimate of the extra costs specific to that airframe.
Basically, the guy who brags about not taking a salary while screwing us over for excess costs on every golf trip to a property he controls is trying to put us on the hook for a minimum cost of $100million per year for the rest of his life and potentially as much as a billion dollars a year. That is the cost to the American taxpayer for the Trump grifts. Personally, I don't want to pay my part of it. I will not think charitably of anyone willing to pay their share.
