A tiny mouse caused a flight cancellation after deciding to board a Nepal Airlines flight from Kathmandu to Bangkok on Monday. Some of the 127 passengers had already boarded the plane, when an air hostess spotted the mouse scurrying across the cabin.

The hostess notified the pilot, who decided to cancel the flight for safety reasons. A mouse hunt is now carried out on the aircraft before it will resume its service.

The Boeing 757 is one of only two aircrafts operated by Nepal Airlines – the second machine is currently undergoing maintenance. The passengers were taken to Bangkok on a Thai Airways flight later in the day.
