I wish it was that FAST!
3-4 hours is normally the flight time a concorde will take from New
York to London, flying between FL550 to FL600 at Mach2.02. The
fastest time clocked by a concorde is 2hr 53 if I remembered.
SIN-LHR will take approximately 9hours plus depending on wind
factors & the temperature at cruising altitude.
a B744 flight time is around 14hrs flying at Mach 0.86.
SIA/BAW flew the thrice weekly service between SIN to LHR via BAH
.which was around 1977 to 1981. shortly after which Changi Airport
was commissioned & PLA relinguished to RSAF.
The reasons which the service was cancelled was many & varied
,but mainly noise and poor load factors which did not recover the
extremely high operating costs.
It only seats 100 pax,no cargo.
Please correct me if I'm wrong as all this is from my old brain
cell memories .
oh, btw, the concorde body expands between 6 to 8 inches at max
cruising speed.
Suddenly u can see n put ur flat palm between panels which u
normally cannot on e ground. Same for the SR-71. It expands
12inches.!!
