Question

At What Maximum Height, Aeroplane flies?

Answer 1

i'd tell ya but then i'd have to kill ya.

Answer 2

Experimental planes have flown to the limits of the atmosphere but are they really aeroplanes?

Answer 3

Manned aircraft have reached altitudes of over 85,000 feet in the SR-71 Blackbird.

An un-manned NASA flying wing, the Helios, has also reached those heights in sustained flight using solar powered propellers.

Commercial Jet Liners operate at a maximum altitude of between 42,000 and 45,000 feet.

The latest Business Jets boast that they can operate above 50,000 feet.

Answer 4

Depends on the airplane. I believe passenger jets have a cruising altitude of 35,000 feet, and I know that the x-15 could reach the edge of space (about 60 miles or 100km).

Answer 5

Upto 60,000 feet fighter aircrafts

Upto 40,000 feet commercial aircrafts.

Answer 6

The SR-71 had a absolute altitude of 85,135 feet

The U-2 has a Service Altitude of 85,000+ feet

Commercial jets cruise up to around 45,000 feet, however, some are rated above 50, 000 feet.
