Mr P.R. Street established Peak Sailplanes Ltd at Chapel-en-le-Frith, Derbyshire, in 1962 to build Peak 100 two-seat sailplane that had previously been designed by the Bedford Sailplane Group. It was built in a converted cotton mill in Chapel-en-le-Frith and had its first flight at Cranfield, Bedfordshire on 5 February 1963.
It was the intention to put the Peak 100 into production and work commenced on the jigs that would be required.
Mr Street joined Slingsby Sailplanes as Managing Director in 1964 and Peak Sailplaned changed its name to Sailplane & Engineering Services Ltd, specialising in glider repair and trailers, from Holmfield Rd, Burbage, Buxton, Derbyshire.
