From what I've heard, Qatar is really supportive of terrorism, so I wouldn't trust any plane that's been in their ownership. Again, I hope Trump knows what he's doing, because I sure don't.
No matter what Trump decides to do, we need to get a new Air Force One. The one the President uses right now is almost forty years old. It's about as safe as a terrorist jet anyway. I used to binge-watch air crash investigation videos religiously, and I can tell you that Trump needs to get a new jet as soon as possible.
