The Queen's Commendation for Valuable Service (or King's Commendation for Valuable Service) is a British civilian and military award that recognises meritorious service during, or in support of, operations. Commercial and test pilots have received the award in recognition of extraordinary flying during extreme conditions.
The holder is entitled to wear the emblem of silver oak leaves. This should be worn in a similar manner to a mention in despatches. If awarded for services in a theatre for which a campaign medal or a clasp has been granted, is worn on the ribbon of the appropriate medal. If the award is made for services out of theatre or in a theatre for which no campaign medal or clasp has been granted the emblem is to be worn directly on the coat after any medal ribbons.
Restriction on number of emblems worn: only one emblem for each category of award may be worn on any one medal ribbon.
It has been awarded, for example, to the co-pilot and to a flight attendant of British Airways flight 5390 and to test pilot Eric Brown.
