Basically, the higher you go the thinner the atmosphere. Therefore, there is a reduction in drag, which decreases fuel comsumption and thus increases range and efficiency, as well as diminuishing friction stress which damage the aircraft.
Yes, aeroplanes fly in the troposphere
with in 48 hours u can fly in aeroplanes.
then there is no point of them
