Just a snippet from Treble One's history:
In 1955 the first Hunters had arrived, and two years later No 111 Squadron was nominated as the official RAF aerobatic team. At first the team, known as the 'Black Arrows', flew five and then nine aircraft until, at the 1958 Farnborough airshow, the Squadron, aided by No 56 Squadron, entered the record books when it successfully looped twenty-two aircraft! In 1961, the unit converted to Lightnings, successive marks staying until 1974 when Phantoms arrived. Following a move from Coningsby to Leuchars, the Squadron re-equipped with ex-Royal Navy Phantoms and these survived until the early 1990s when Tornado F3s became the Squadron mount.
'Blue Diamonds' was the name given to 92 Sqdn - I believe with Brian Mercer as the original team leader. A great team - as they all were.
