Has Virgin one of the best safety records for an airline? I am not aware of any major problem with them since their inception
One of the best - only one incident I can find on http://www.aviation-safety.net/database/ and even this garners praise for Virgin...
Remarks:
The accident occurred when the aircraft, which had a landing gear problem on its first approach to Heathrow Airport, carried out an emergency landing on Runway 27L with the left main landing gear only partially extended. The flight crew responded to the in-flight emergency with commendable judgement and conducted a skilful landing, with the Airport Emergency Services in full and effective attendance. The evacuation was completed with minor injuries to 5 passengers and 2 crew members.
