Joseph Barcroft researching chemical weapons at Porton Down:
"On one occasion, one of his female assistants travelled by train from his laboratory in Cambridge carrying a canister of poison gas. The canister began to leak in the compartment. She attached it to a piece of string, hung it out of the window and completed her journey to Porton."
Stanley Lovell researching bombs at the Office of Strategic Services:
"Cats, it was suggested to the OSS, always land on their feet, and will go to any lengths to avoid water. Why not wire a cat up to a bomb, and sling both cat and attached high explosive below to a bomber? When flying over enemy sips, the explosive cat would be released. The cat would be so concerned to avoid landing int he water that it could, it was argued, be virtually certain of guiding the bomb onto the deck of enemy warships. Exerpiments with flying cats soon proved to the supporters of the project that even unattached to high explosive, the cat was likely to become unconscious long before Nazi decks seemed an attractive landing place."
