Two scorpions that scurried across the cabin aisle of a Vietnam Airlines plane panicked passengers and delayed the domestic flight by two hours.
All 170 passengers left the Boeing 777 after the poisonous creatures were caught shortly before the jet had been due to take off from the central city of Danang for Hanoi today.
The flight was delayed for two hours as the airline checked the rest of the plane and its luggage.
But passengers shrieked again when the jet reached Hanoi and four more stowaway scorpions were found in an overhead compartment.
In April, a Vietnam Airlines flight to Tokyo was delayed for hours after a white mouse went missing on the plane. It was later found and destroyed.
