Once upon a time, Aerospatiale was designing a plane variously named ATSF and Alliance. It was supposed to have 4 engines well separated on wing (unlike paired engines of Concorde) and be bigger than Concorde: fuselage width 349 cm (Concorde 288 cm), with normal passenger payload of 200 passengers, including 160 coach seats in 32 rows 5 abreast at 35 inch pitch and 40 first class seats in 10 rows 4 abreast at 40 inch pitch (Concorde 100 passengers in 25 rows 4 abreast at 37 inch pitch).

It was also supposed to have 12 000 km range.

How was Aerospatiale proposing to achieve that range? Did they release any numbers as to MTOW, OEW, fuel load?
