Trump detours in UK / Air Force One old plane / NATO return trip flight plan change

The most concrete factual gap is the final leg. The updated Guardian says Trump “later boarded the new plane at Mildenhall air force base…for the trip back to Washington,” and Bloomberg’s headline says he “switch[ed] Air Force One planes” in the UK. Fox and Newsmax do not state that final switch; Fox frames it as “flying old Air Force One back to DC,” while Newsmax says he “flew home…on an old baby blue Air Force One plane.” The biggest extra security detail appears only in Newsmax/AP: it says images show the Qatari-gifted jet lacks “some of the same missile detection and countermeasure systems,” that the old plane’s transponder was not trackable early in flight, and that other leaders’ flights were trackable. None of the Guardian or Bloomberg items, and not Fox, include those specifics. Word choice also diverges: Guardian calls it a “new, Qatari-gifted aircraft” and a “controversial gift” raising “security and conflicts of interest,” while Fox mostly uses Trump’s showcase language, “brand new, and truly spectacular,” and says troops could see it because it is “truly magnificent.” Newsmax uses more risk-heavy language than Fox, leading with “Amid Iran Threats” and “surprise swap.” The unasked question across all versions: if security concerns were not the reason, what exact operational reason required Trump to fly the older jet from Turkey to Mildenhall and then, per Guardian/Bloomberg, switch back to the new plane for Washington?
