# What is the upper altitude limit for propeller driven aircraft? [duplicate]

Is it possible to fly 100 kilometers with a propeller driven aircraft? and if not what is the limit of a propeller driven aircraft?

• 100 Mm (megameters) is a third of the way to the moon, 100 km is already considered space – ratchet freak Aug 6 '14 at 20:50

• this is also true for **any** other kind of propulsion that's quite wrong. – Federico Aug 8 '14 at 6:28
