Question why does it take a shorter time to fly back from the East to west on airplane......
Answer Salman
Your question is a little vague, so I am going to assume you mean... why do aircraft fly faster in the easterly direction. The answer is that the jet stream blows from west to east at 10 km altitude. So an aircraft flying from west to east gets a boost from the wind. An airplane flying east to west has to fight a headwind. Wind makes a big difference to aircraft, and though the jet stream wanders, it is very consistent as to direction.
