No desire to read? Now you can see the same thing:Many people ask themselves: why is the entrance to and exit from the aircraft made on the left, while the doors are located on both sides of the fuselage? Indeed, it has long been accepted in aviation that the left side is intended for passengers, and the right side is for official needs – loading food and luggage. Some mistakenly think that this was done for the commander of the aircraft: supposedly it is more convenient for him to see and control the reception and disembarkation of people. A single standard is used in almost all airports in the world. In the first half of the 20th century, at the dawn of aviation, chaos reigned in this matter, but in 1940 they adopted general rules that are still in effect today.
