From New York Post (caution: tabloid):
President Trump abruptly announced Wednesday that he would not fly out of Turkey aboard his luxurious new Air Force One — stoking speculation that the Qatar-donated jet may be vulnerable to Iranian fire as the war resumes.
Trump instead departed the annual NATO summit using the older model of Air Force One, which he had stopped using last week in favor of the $400 million “palace on wings” that he has proudly boasted about acquiring. The president claimed on social media the plane switch was so that US troops in England could “tour” the upgrade — but speculation swirled after he spent the day repeatedly mentioning Iran’s interest in killing him.
