I think the fam has been [heavy CO2 spewing - the National Forests just love it] running the 757 while the Boss was away.
From what I've read on airline sites it's been in storage at a Long Island airport for the past few years. After all, Trump didn't anticipate needing it until 2025. There's a lot of work involved in getting it back into the service and as of December a search was on for at least one new engine needed to get it back into the air and to a maintenance facility in Louisiana. I assume a something has been done since December. Not surprisingly, tracking the Trump 757 tail number has been blocked from sites at the owner's request.
