Cracked window on Boeing 737 forces All Nippon Airways flight to turn back

A domestic flight operated by a Japanese carrier returned to its departure airport after a crack was found in a window in the cockpit of a Boeing 737-800 plane. The crack was discovered about 40 minutes after take-off and was located in the outermost layer of tempered glass on the cockpit window. The airline is investigating the cause of the crack and has reported the incident to the relevant authorities. Boeing’s 737-800 model is known for its reliability and safety record but has faced scrutiny after a recent mid-air incident involving a different model, the 737 Max 9.
