The stratosphere is situated between about 10 km (6 miles) and 50 km (31 miles) altitude above the surface at mid-latitudes, while at the poles it starts at about 8 km (5 miles) altitude
Normally, temperature decreases as altitude increases. In a temperature inversion, the temperature increases as altitude increases, up to the level of air that is causing the inversion. See "Temperature change as altitude increases?" for info on how temperature normally decreases with altitude when there is not a temperature inversion.The rate at which the temperature goes down is down 1.1 degrees celsius for every 500 feet you go up.
The cruising altitude of the Space Shuttle depends on its mission. Since the Columbia disaster, with the exception of the last Hubble Servicing Mission in summer 2008, the cruising altitude has been equal to that of the International Space Station, approximately 340 km (211 miles). The highest a Space Shuttle has flown has been on the servicing missions to the Hubble Space Telescope, at approximately 600 km (372 miles). For a sense of perspective, on a 16 inch diameter globe 372 miles translates to .7515 of an inch. The maximum theoretical altitude for the Space Shuttle has been reported as 600 miles. On a 16 inch diameter globe 600 miles translates to 1.2121 inches.

If the velocity is constant, then the acceleration is zero.
Approx. 900 km/h or 560 mph at cruising altitude.
A jumbo jet must reach a speed of 360 km/hr (225 mph) on the runway for takeoff.
The TROPOSPHERE (up to 10 km altitude, where we live) and the STRATOSPHERE (10 to 50 km altitude, where jet aircraft fly).
The Dreamliner´s groundspeed at cruising altitude is about 480kts. / 550mph. / 890 km/h.
Fighter jet with ease. Nearly all fighters are able to fly at mach speeds (faster than the speed of sound) and if a jumbo tried that it would break up. jumbo jets usually cruise at around mach 0.85 (567 mph, 913 km/h, 493 knots) which is well under the speed of sound (around 1000 km/h)
Chances are you would miss it completely.
No. That is 100 km per minute, or 6000 km per hour. The cruising speed for a passenger jet, for comparison, is around 1000 km per hour.
The A380 has a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude), its maximum design speed is Mach 0.96.
According to Boeing, the cruising speed of their jets are as follows:MD 90 -- Mach 0.76, or approximately 500 mph (812 km/hr)707 -- 550 mph (885 km/h)727 -- 570 to 605 mph (890 to 965 km/h)737 -- Mach 0.82, or approximately 550 mph (885 km/hr)
If a commercial passenger jet can travel up to 970 km per hour at an altitude of 30,000 feet, it would take just under 3 hours to travel 2,902 kilometers.
0.89 Mach (590 mph, 950 km/h, 512 knots) at 35,000 ft (11,000 m) cruise altitude
