The higher an aircraft is the less air in the atmosphere. this means less air resistance which means you can go faster with less effort. also less air means less fuel burnt for same power. this saves fuel. for this reason most aircraft will operate at high altitudes
There are also fewer obstructions at high altitude than there are at 1000 feet.
It reduces climb performance.
It was a high altitude, very fast recconnaisance aircraft
The SR 71 was a very secret high speed, high altitude reconnaisance aircraft. Only 32 were built, at enormous cost.
An altimeter (altitude meter) tells the pilots how high the aircraft is flying. There are 2 types of altimeters commonly used in aircraft: pressure altimeters and radar altimeters.
That is condensation from hot engines in cold air.

High machinery
The SR-71 is a high-altitude, high-speed reconnaissance aircraft. It carries high performance cameras used in spying.
Well I think iM not sure that high altitude discharge its when the charged solar particles acumulate and the lighting occurs and the gorgeuus celestial phenomenon resulting from this effect its the aurora
Cruising altitude is an economical height for an aircraft to fly. It is also a choice made in view of other aircraft routes.
Aircraft typically arrive at an altitude of around 30,000 to 40,000 feet to operate and fly.
The service ceiling of an aircraft is the maximum altitude that the aircraft can safely maintain.
