i was doing some progress in flight dinamics (this big bird is FAST, stall speed still a bit low but the rest it's ok.) and suddenly i thought "what if?..."
"G-159C Gulfstream I-C
Stretched regional airline version. Five G-I aircraft were converted into Gulfstream I-Cs, by having the fuselage lengthened by 10 ft 8 in (3.25 m) to provide seating for up to 37 passengers."
we stretch the things a little bit
thanks a LOT to the G-159 HISTORICAL RESEARCH MUSEUM
