Double Enterprise delivery

Enterprise Holdings, parent company of car rental companies Enterprise-Rent-A-Car, National Car Rental and Alamo Rental Car (being the best known names when you arrive at the airport). Originally founded in 1957 (hence the cherished number N57EL) and re-named Enterprise in memory of one of the founders that served on the USS Enterprise (rather than a Star Trek fan)
G500 N57EL (72027) and N528GD (72028) were both delivered from Savannah on the 27th to St. Louis (base of Enterprise). Not sure if these will be replacing the current fleet of a pair of G450s or not. The old N57EL (4221) has taken up N47EL while the old N56EL (4230) has recently taken up N53EL so there's a good chance the 2nd G500 will take up N56EL in due course. They will be joining the single G550 N70EL (5510). To complete the story, the earliest aircraft I can find in the fleet were Dassault Falcons about 10 years ago.
