I've just seached faa.gov for John Travolta, and amazingly found him.
Type ratings:
P/B-707 P/B-720 P/CE-500 P/G-1159 P/HS-125 P/LR-JET
Limits:
ENGLISH PROFICIENT.AUTHORIZED EXPERIMENTAL AIRCRAFT: SO-G2.B-707 SIC PRIVILEGES ONLY.CE-500 (VFR ONLY).
But yes, he is just a ME PPL/IR
His B707 SIC-only privilege is interesting. I wonder why?
I know about the concession whereby one could log SIC time in a multi crew aircraft, with just a ME PPL, no IR and no TR, but this is a sub-ICAO privilege limited to the USA only. It was used by some pilots outside the USA but this scheme was stopped a few years ago.
JT does have a 707 TR so why only SIC? Is it that one needs to be an ATP to sit in the LHS of a ME jet of that size? I wouldn't have thought so.
