Shin Meiwa GS
The largest of Shin Meiwa's seaplane designs: the GS (Giant Seaplane).
Planned to carry 120 tonnes or 1200 passengers, while dispensing with the need for the massive (and expensive) ground infrastructure of new airports, the Shin Meiwa GS was probably the last practical design following on from the pre-war massive flying boat mania.
Requiring 6 77,000lb thrust engines and a USB blown supercritical wing, the technology required was not developed and this audacious design was never progressed.
Painted from "Popular Mechanics" 1977.
