The Vickers Viscount G-AOHP was a prominent passenger aircraft operated by British European Airways (BEA). On approach to Copenhagen Airport, the aircraft encountered severe challenges when three of its four engines suffered failures. Investigation revealed that the failure was linked to a malfunction in the anti-icing system, which is crucial for maintaining engine function at high altitudes where ice can form on engine components. The failure of the anti-icing system, particularly in the variable pitch propellers used by the Viscount, created a hazardous situation for the crew as they attempted to land the aircraft safely. 

As the pilots dealt with the loss of power, the aircraft made an emergency landing at Ballerup, just outside of the city. The skillful management of this crisis by the flight crew was paramount in ensuring the safety of all aboard. In a testament to their training and composure, the landing was executed without injuries or loss of life, even amidst the serious mechanical failure.

Following the incident, aircraft safety protocols were revisited, particularly those relating to icing conditions. The event highlighted the need for robust anti-icing systems as part of air travel safety measures. Additionally, it led to ongoing discussions within the aviation industry regarding the reliability of turbine engines and the importance of thorough inspections pre-flight due to icing conditions affecting engine performance.
