What causes a cracked windshield?

There are a number of reasons as to why aircraft windshields may crack. Designed to withstand huge variations in temperature and pressure, windshields are made of several layers of glass that are designed to be extra durable. The glass should be able to withstand the impact of a bird strike.

However, the windshield is not indestructible. In fact, windshields may suffer cracks more often than you might think. In fact, a common cause of aircraft windshield cracks are actually severe hailstorms.

A windshield may also crack due to incorrect heating. This occurs with modern aircraft that have electronically heated windows. The glass sometimes cracks due to a short-circuit. The age of the aircraft and the number of flight cycles can also be a factor due to stress levels put on the glass over a long period of time.

It’s great to see that passengers were able to resume their journey within the same day rather than wait a 24-hour period. Hopefully, Rossiya’s 777 will be back in the air sooner than later.
