Flying on a plane is always comfortable as well as opulent. Massive distances can be covered up very easily. You have travelled many times in flight but have you ever thought of why the window of a plane is always round or oval in shape????
In 1950, when people started travelling through plane then the windows of planes were square in shape. In 1953, 2 Planes were crashed in which 56 died. The reports claimed that the reason for the accident was the square shape of windows because four edges of it made the windows weaker. In this sort of windows, there are four weak spots which can be cracked in the air because of air pressure.
The new model proposed to make the windows round or circuitous so that the pressure gets distributed which reduces the risk of getting windows damage.
