Spiral Plastic Binding. Zustand: Very Good. No Jacket. 1st Edition Reprinted. Important proposal by Barnes Wallis, arguing that the present methods of attacking German industry are effectively thwarted by dispersal, therefore what is needed is concentrated attacks on sources of power using very large bombs. Anticipating the use of the Bouncing Bomb and the "Tallboy" bomb developed by the author. Originally published 1940 and as printed on cover "Copy of the Original Report Reproduced 1970". Research indicates that the Imperial War Museum hold a similar 1970 copy in this format. Clearly a very small number of these copies were printed and bound. c.150pp., including numerous diagrams and photograph. Some of the printed pages are a little faded but the whole report is fully legible. An original signature of Barnes Wallis has been neatly stuck under his name on the title page "Yours sincerely B.N.Wallis". Overall condition Very good and rare. Signed by Author(s).

Zustand: Very good plus. First Edition. Rare presentation copy of this paper by the renowned airship engineer and inventor of the bouncing bomb, signed "with the Author's Love to his Assistant" - his wife and longtime airship confidante Mary (Bloxham) Wallis. Though later generations know him best for inventing the "bouncing bomb" used against German dams in World War II, in the 1920s Barnes Wallis's heart still belonged to Rigid Airships. When he was not designing them for the Airship Guarantee Company as part of the Imperial Airship Scheme (for purposes discussed in this paper), he was describing them to his beloved future wife, Mary (Molly) Bloxham, whom he met in 1922 and married in 1925. As Bloxham had just begun medical studies at University College London when they met and Wallis was twice her age, Bloxham's father wisely forbade him to write to her about anything but mathematics. Airships entered their correspondence almost immediately and offer a reliable index of both parties' moods and growing affections: "You see all my heart is in Airships," Wallis explained, and later, "I'm in a way rather depressed about Airships." Bloxham replied faithfully: "I am so sorry about the Airships, Barnes," and on better days, "Barnes, I am so awfully glad about the airships." Wallis constantly praised and encouraged Bloxham's progress in math and engineering ("you ARE most awfully brainy"), in large part because the more she learned, the more conversations they could have about airships: "I think when we have done enough trig. I shall have to start writing you a book on Airships, so that I can talk to you about them freely." Both in his private correspondence and in this paper, Wallis was firmly optimistic about the safety of airships and the advantages of hydrogen over helium: "In a modern suitably designed airship the possibility of its catching fire is so small as to be almost negligible," he explains; "we are definitely of the opinion that hydrogen is no longer a source of danger in an airship." While Wallis was designing His Majesty's Airship R100 for the Airship Guarantee Company, a sister ship, the R101, was simultaneously in development by a separate design team at the Royal Airship Works. The latter embarked on its first overseas flight in 1930 and promptly crashed and exploded. Wallis, a practical man despite his faith in airships, moved on to designing aircraft fuselage and eventually bombs, which also explode, but on purpose. A unique association copy of a rare publication in aeronautical history. 9.5'' x 7.75''. Original saddle-stapled printed wrappers. 13, [1] pages followed by 9 black-and-white airship diagrams. Inscribed by Wallis on front wrapper: "With the Authors Love / to his Assistant. / BNW." Moderate foxing to wrappers and scattered throughout.
