First revenue flight is supposed to be c. May 15, 1995.

Both the PW4084 and Trent 800 for the 777 were supposed to flight test
on 747 #1, which Boeing leased back from the Seattle Museum of Flgiht
for the tests.  I never heard of it actually happening, though I can't
quite imagine it making its maiden flight on a still-uncertified
airframe.

GE used a 747 that they (GECC) owned and had leased to Pan Am for the
GE90 flight tests.
