"Of all the transport devices that mankind have so far invented, you realize that the aircraft is the safest of all.
I've heard that.
I think the chances of a fatal accident involving people are cars, trains, and aircraft in descending order.
According to US National Transport Safety Board(NTSB) the chances of a serious accident happening with commercial aircraft is 0.009%.
According to a report by some Dutch think-tank, a grave aircraft accident may happen to a person who flies once a day, only once in 10 thousand years.
When flying an airplane, the most crucial period is 3 minutes after take off, and 8 minutes before landing. The total of 11 minutes is called the 'Crucial 11 minutes'.
You're saying take off and landing is the more dangerous period.
When flying at high altitude under normal cruising speed, the airplane is in a stable condition.
At take off, the airplane climbs up to say 10 thousand meters in 3 minutes, at landing, it starts to descend by slowing the speed from 8 minutes before touch down, the aircraft is in a very unstable condition."
