A plane which crashed and seriously injured some officials of Swindon Town FC ran out of fuel, an Air Accidents Investigation Branch report concluded.

The Cessna came down near Denham, Buckinghamshire, in August 2006. The club's former chief executive and a investor were on board.

The AAIB report said the plane was not capable of safely completing the trip without refuelling for the return trip.

It also noted the pilot had consumed alcohol but its effect was not known.

Swindon Town's then chief executive Mark Devlin and his son Stan were injured in the crash, as well as marketing manager Mike Sullivan, who has since left the club.

Also taken to hospital was investor Bill Power, an unnamed passenger and the pilot, 60, who was seriously hurt.

The plane had taken off from Denham airfield earlier in the day and was returning from the first match of the season at Hartlepool United when the crash happened shortly after 1900 BST.

All the injured were taken to Wexham Park Hospital in Slough The AAIB report said the pilot was properly licensed, the aircraft was fully serviceable and the weather was suitable for the flight.

However, for the payload being carried, the aircraft was not capable of safely completing the round-trip flight without refuelling at Durham Tees Valley aerodrome.

The pilot had consumed alcohol during the day although the amount detected was not considered to be a major contributory factor in the accident and the effect on his decision making and aircraft handling ability was not known.

It concluded the accident was caused by fuel starvation of both engines with the right engine ceasing to produce power and the left one operating at reduced power or stopping.

Control was lost when the aircraft stalled.
