From the Red Arrows history section of the RAF Website -
Red Arrows
The Gnat, which had flown 1,292 displays, was replaced by the BAE Systems Hawk, a modified version of the RAF’s fast jet and weapons trainer, for the 1980 season. Also that year, permission was given for the team to have the motto Eclat – meaning excellence.
For my two-penneth, it's an excellent program which my whole family has been able to sit down and watch and find very interesting and enjoyable; for me as a PPL holder, my wife who puts up with my unhealthy obsession with aviation and my kids who have seen many displays and met the pilots several times over the past few years!
