Royal Air Force — Flight XM645

A Royal Air Force Avro Vulcan B.2 bomber exploded in mid-air over the residential town of Zabbar after a botched landing attempt at RAF Luqa. During the initial approach, the aircraft undershot the runway, shearing off its port undercarriage. The captain took control and attempted to climb for a second approach, but the impact had also pierced a fuel tank in the starboard wing, leading to a fire and a catastrophic mid-air explosion. The two pilots successfully ejected, but the five rear crew members were killed. Debris and burning fuel rained down on the town, killing one civilian on the ground and injuring 20 others.

Report

Investigation Summary

The flight was a routine exercise from RAF Waddington to Malta. During the final approach to RAF Luqa, the captain, Flight Lieutenant G. R. Alcock, allowed the co-pilot, Flying Officer E. G. Alexander, to fly the aircraft despite Alexander not being adequately briefed on the specific challenges of Luqa's short, sloping runway. The aircraft made a hard landing, undershooting the runway and causing the port wing to strike the ground, which sheared off the main landing gear. Captain Alcock took over control and applied full throttle to all four Olympus engines to climb away. However, the impact had breached a fuel tank in the starboard wing, igniting a fire. As the aircraft circled for an emergency belly landing on a foamed runway, the fire intensified. Realizing the aircraft was lost, the pilots ejected. Seconds later, the Vulcan exploded. Because the Avro Vulcan was only equipped with ejection seats for the two pilots, the five rear crew members (the navigator, radar navigator, air electronics officer, and two supernumerary crew) were unable to escape through the crew door before the explosion. The main fuselage fell into a field, but the fuel tanks and wing sections landed in Sanctuary Street, Żabbar, causing extensive fires that damaged over 100 buildings and cars.

Final Conclusions

The official inquiry concluded that the crash was an avoidable accident involving a serviceable aircraft. The primary cause was pilot error, specifically the captain's decision to allow an inadequately briefed co-pilot to perform the landing at a challenging airfield. The report further characterized the captain's handling of the aircraft as negligent. The investigation noted that the five rear crew members had no chance of survival once the fire led to the mid-air explosion, as they lacked ejection seats.

Systems & Failure Modes

i

Ejection Seats

Only the pilot and co-pilot were equipped with Martin-Baker ejection seats; the rear crew members were required to bail out manually, which was impossible during the mid-air explosion.

i

Fuel System

A fuel tank in the starboard wing was pierced during the initial runway impact, leading to the fire that eventually caused the mid-air explosion.

i

Bristol Siddeley Olympus Engines

The aircraft's four engines remained functional after the initial impact, allowing the pilot to briefly climb away from the runway.

Interesting Facts

  • 01The Avro Vulcan B.2 only provided ejection seats for the pilot and co-pilot; rear crew had to exit via a manual door.

  • 03Over 100 houses and shops in Żabbar were damaged by the explosion and subsequent fires.
  • 04The aircraft was completed in March 1964 and was considered fully serviceable prior to the hard landing.
  • 05A house in Żabbar that was destroyed in the crash was rebuilt by the RAF and named 'Vulcan'.

Safety Actions & Advisories

Crew Briefing Requirements

The inquiry emphasized the necessity for comprehensive briefings when handing over control to junior pilots, especially at airfields with non-standard runway profiles.
