Yes, John Travolta operates a 707-138B.
He employs 2 captains and 2 flight engineers (one F/E does A&P duties).
John himself has a CPL and a CE-500 type rating.
Originally was not "type rated" (as he "acts" as F/O) on the 707.
I assume he recently obtained a "second in command 707 type rating" to fly out of USA.
