I'm reading the 2020 Maxwell trial transcripts and both the pilot, Larry Viskoski, and the first victim the govt put on the stand, "Jane," testified under oath that Epstein was a repeat visitor to Michigan and to the Interlochen School of Music in Traverse City, where Epstein had apparently attended at some point and from which he and Ghislane Maxwell initially made contact with "Jane" at the age of thirteen.

Just in case anyone else was wondering what Epstein was doing in Michigan, of all places. Turns out he went at least once a year, if not more often. What this tip is alleging is entirely possible, at least from the geographic standpoint.
EDITED TO ADD: Incidentally, this link is to the same portion of the transcript, Day 2 of the trial, where the same pilot also testifies under oath that Trump flew on Epstein's jet "a number of times" or "more than once" (pp. 105-106):
Q. Donald Trump, before he was president, also flew on Epstein's flights; isn't that right?
A. Yes, he did.
Q. He flew on them a number of times; right?
A. There was more than once I believe, yes.
Q. Sometimes he flew with his family members, too; right?
A. I don't know -- I don't remember that. I certainly remember President Trump, but not nearly the other people associated with him. Like I said, if it was something special that would get embranded in my head, I certainly remember the president.
