A plane has with 173 people on-board has been forced to prepare for an emergency landing due to a crack in the cockpit windshield.
The Boeing 737 took off from Novosibirsk, Russia, towards Sanya, southern China, when crew noticed the rupture in the glass mid-air.
It was decided as a result that the NordStar flight would have to make an emergency stop in Krasnoyarsk International Airport, Siberia, RT reports.

It is thought that fire trucks and an ambulance are already arriving at the airport as a precaution.
A spokesperson at the local transport prosecutor’s office told RT that the crew had received a ‘technical problem’ signal from one of the indicators on-board the plane.
Tiger shot dead after ‘killing 13 people’ in IndiaCockpit windscreens are formed of several layers and are designed to withstand air pressure of up to 500 knots and accidents such as hitting a bird in flight.
But they are not indestructible, with windscreen cracks most likely to be caused by hailstones, or a malfunctioning component within the cockpit.
Issues may also occur if the glass is not heated properly, causing it to short-circuit due to the differences in pressure inside and outside the cabin.
Last year a TUI flight from Gran Canaria to Bristol was forced to make an emergency landing in Portugal as a result of a cracked windshield.
Fortunately no-one was harmed in the incident, although the pilot was forced to drop 20,000 feet from the plane’s cruising height of 30,000 feet in the interest of safety.
In May earlier this year a co-pilot was ‘sucked halfway out’ of his cockpit after the windshield of a Chinese passenger jet shattered at an altitude of 32,000 feet.
Captain Liu Chuanjian told the Chengdu Economic Daily that most of his equipment malfunctioned and the plane was shaking so hard he could not read the gauges.
Fortunately the co-pilot was wearing a seatbelt and crew members were able to pull him back into cockpit with only minor scratches and a sprained wrist.
One member of cabin crew was injured in the flight’s descent but the 119 passengers were otherwise unharmed.
