Originally, the life jacket is for rescuing people but there is a fatal error. We can recognize it from the Ethiopian Flight # 961 accident in 1996 and Ferry Sewol accident in Korea in 2014. The life jacket which is a buoyancy aid prevents to escape from the exit in the water. In the end, wearing a vest to live has hindered the chance of escape. We found out the solution that the Life jacket can be controlled the buoyancy. People can stay under water by pulling a manual switchgear in the emergency situation which is impossible to escape because of buoyancy. Moreover, they can boost buoyancy and float on water by using inbuilt co2 capsules.
