Scumbag ex-Team USA doctor Larry Nassar got the private jet treatment Friday to fly from Michigan to Tucson to begin his federal prison stint ... and TMZ Sports has the photos.
Nassar boarded the plane at Detroit Metro Wayne County Airport in freezing Michigan temperatures -- the fact he didn't get a jacket makes us smile.
Records show the flight lasted 4 hours and 36 minutes. Nassar appears to be shackled and surrounded by law enforcement officials ... so we're guessing it wasn't exactly a Paris Hilton style private jet flight.
