I recently watched a movie and in the movie it stated that the helicopter could not fly to the top of mt.everest to rescue the person stuck on the top. So why can't helicopters fly at such high altitudes?

The U-2 is probably the highest altitude aircraft still flying. The SR-71 could probably fly higher, but it isn't flying any more. The U-2's published maximum altitude is somewhere above 74,000 feet. There is no such thing as so high radar ca...

Doubly so if the movie originated in Hollywood. The world altitude record for a helicopter is 40,814ft, some 11,000 feet higher then Everest, set in 1972 Reference: Wikipedia In 2005 Didier DelSalle famously touched down on the summit of Everest in an AS350 Squirrel Reference: Wikipedia.

What is the highest altitude a passenger aircraft can safely fly? Is it possible to shoot a plane flying at a very high altitude? At what altitude do turboprops fly?

The U-2 is probably the highest altitude aircraft still flying. The SR-71 could probably fly higher, but it isn't flying any more. The U-2's published maximum altitude is somewhere above 74,000 feet. There is no such thing as so high radar can not detect it, since radar can detect things in outer space.

Less air density means less lift. The air density at sea level is 1.225 kg per cubic meter (Source). However, as you go higher above sea level, air density begins to decrease. This is why people sometimes have difficulty breathing at higher altitudes in mountainous regions.

The real reason helicopters don't routinely fly to those altitudes is that they're not designed to. As with everything in aviation, performance is a trade off between engineering, aerodynamics and commercial pressures. There's a big market for helicopters that can fly up to, say, 12-15,000ft. The market for helicopters capable of rescuing climbers from the top of Everest is, at best, limited, and the technical demands of building a craft routinely capable of such a flight will push the costs up dramatically. In short, they don't because nobody will pay for it.

Failure of an aircraft's components at extremely high altitude is not so much a matter of breakage as it is a failure to function so that flight can continue. The failures are those of lift (by the wings), thrust (from the engines) or control (by flight control surfaces).

what is the highest a helicopter can fly?
There is a big market for Helicopters that can fly up to 12 to 15 feet.
