239 pp, 8 1/2" H. Blue cloth with gilt lettering on spine. B&w map, photographs. Inscribed on front pastedown: "With Sincere Good Wishes / & Thanks. / James J. Hinton". Mr. Hinton was associated with time trials of the Bluebird and is referenced in the book with at least one notation and a photograph (mislabelled 'Hunter'). The following quote is from an article in "Sports", November 1957 - "Donald Campbell Lives for Speed", by Diana Bartley - "(T)hat the blue-eyed youth who seems endlessly preoccupied with the enormous bright yellow rubber balloons which form course markers clearly visible to Campbell even at speeds beyond 200 m.p.h. is Jim Hinton, on temporary leave from atomic research activities with the Dunlop Rubber Co. Jim is the designer of the functional buoys and master of the course". "Into the Water Barrier" is "the personal story of Donald Campbell, only son of the late Sir Malcolm Campbell. It tells how Donald suddenly determined to try to improve his father's world water speed record of 141.74 m.p.h. for Britain when he heard of an American challenge. (The) new Bluebird was launched on Lake Ullswater in February, 1955, and after four months of further research and modification a new world record of 202.32 m.p.h. was established on 23rd July. Donald regards the development of his jet Bluebird as a scientific venture that could lead to the development of a high-speed offensive Naval weapon."
