The airliner version of the HS.1101 in the early colours of British Airways.
This was the commercial version of the MPA aircraft posted earlier. There are a few changes, notably the dorsal engines are slightly different and both these pods and the ventral engine pods have longer intakes. The top of the tail is slightly different too . The cockpit windows were redesigned too. This Mach 1.15 airliner has the same VG wing, it could carry 160 passengers (carried 4,5 and 6 abreast in the waisted fuselage) over 2,500 nm, all-up weight was 269,000lbs. It was designed to cruise at 40,000ft with no shock wave reaching the ground allowing unrestricted supersonic flights. I have no idea what the engines were, possibly Olympus or perhaps another type of reheated turbofan (maybe Spey?), almost certainly though a Rolls-Royce design by this date (early-mid 1960s). With the VG wing this would have been a complex type but the relatively low supersonic speed and no boom might have been selling points for economics when airlines were still quite iffy about supersonic flight and the costs. But in the real world I don't think Mach 1.15 would have saved that much over the total time of the flight (block speed) once the climb and let-down are completed, to make it worthwhile in the extra fuel and weight of the VG wing and the small cabin and passenger load. I'm assuming the MPA version was meant for burst speed rather than supersonic cruise. Also, the high dorsal engines would have been awkward to service without special gantries etc. Even so it was a looker!
