Re: Saunders-Roe marine airliner project
German Wikipedia site gives range as 4800 km or 2600 nm - barely Shannon to New York.
From Putnam's 'Saunders & Saro', page 311.
"...in the 1950s... J. Dundas Heenan, a consultant engineer to... P&O... suggested that P&P were interested in... a very large 1,000 passenger flying boat with accommodation of a similar to... inter war [flying] boats. Provision for freight and mail... was also required.
The... route for this aircraft was Britain-Australia, intended stage lengths were nearly 2,000 miles, and the round trip was to last one week
Saro's response was... 670 tons all-up weight... 24 RR Conways of 18,500lbs thrust [each]...,speed 454mph at 30-40,00ft, range 1,880 miles.
Six passenger compartments were planned, for day and night use.Bars and dining rooms were included, aswere lounges and even dressing rooms.
Plans... for a flight crew of 7, with... accommodation on the lowest of five decks, and... a special office for the purser. There was to be a crew lounge and 40 cabin crew...
... main base was to be Southampton with staging points at Alexandria, Karachi, Calcutta, Singapore, Darwin, and Sydney.
The outbound journey was to take 45hrs, and the return leg 48hrs.
Gunston, in 'Giants of the Sky, quotes the range as "4,200 miles at 510mph". He also mentions a "T-Tailed version with 16 BE.25 turboprops"
