Boeing Airliner Studies - 1990-2010

[Schorsch]

Hi.
Does anyone know any Boeing studies from the mid 1990ies?
I came across some cross sections from projects called G1/G2 and G3/G4.
Does anyone know specifics about those proposals?

I'm familiar with the Boeing New Large Aircraft (NLA), which along with the McDonnell Douglas MD-12, would have been a rival to the Airbus A380. The Model 2020 Super Clipper was also envisaged in the 1990s:

By the way, what does the letter G in G1/G2/G3/G4 stand for?
