Concorde's pressurisation was set to an altitude at the lower end of this range, 6,000 feet (1,800 m). [129] Concorde's maximum cruising altitude was 60,000 feet (18,000 m); subsonic airliners typically cruise below 44,000 feet (13,000 m). [130] A sudden reduction in cabin pressure is hazardous to all passengers and crew. [131]
For example, Concorde had very high drag (a lift to drag ratio of about 4) at slow speed, but it travelled at high speed for most of the flight. Designers of Concorde spent 5000 hours optimizing the vehicle shape in wind tunnel tests to maximize the overall performance over the entire flightplan.
Concorde was originally designed for cruising speeds up to Mach 2.2, [55] but its regular service speed was limited to Mach 2.02 to extend airframe life. [56] One of Tupolev's web site pages states that "TU-144 and TU-160 aircraft operation has demonstrated expediency of limitation of cruise supersonic speed of M=2.0 to provide structure ...

However, some school zones can have posted speed limits requiring drivers to lower their speed to 15 mph, the department’s website states. What does ‘when children are present’ mean?
The maximum speed without afterburning was Mach 1.05. [6] The P.1 prototype of the English Electric Lightning, powered by non-afterburning Armstrong Siddeley Sapphire engines, exceeded Mach 1 on 11 August 1954. A week previously, on 4 August, the P.1, WG760 flown by Roland Beamont on its maiden flight, had unknowingly exceeded Mach 1 in a climb ...
