On a gloomy Saturday afternoon, the staff at the Saroj Super Specialty Hospital in Delhi broke down and started praying anxiously as lives of over 100 patients hung by a thread amid rapidly depleting oxygen supply.

An oxygen tanker had reached the hospital after the staff spent hours running around in search of supplies and making frantic calls to the government and police. But it could not enter the area where the hospital's oxygen tank is. The problem: its larger-than-normal size. The solution: an excavator, which broke down a portion of a wall.
