''Weapons of Mass Destruction: An Encyclopedia of Worldwide Policy, Technology, and History'', ((Google Books )), ABC-CLIO, 2005, p. 304, (ISBN 1-85109-490-3).〕 The fleas were loaded into two types of munitions and dropped from the air.〔 The E14 bomb and E23 bomb, which could be clustered into the E86 cluster bomb and E77 bomb, respectively.〔 When the cluster bombs reached 2,000 or 1,000 feet (600 or 300 m) the bomblets would drop via parachute, disseminating their vector.〔 The E14 was designed to hold 100,000 fleas and the E23 was designed to hold 200,000 fleas but the E23 failed in over half of the preliminary Big Itch tests.〔 E23s malfunctioned during testing and the fleas were released into the aircraft where they bit the pilot, bombardier and an observer.〔 As a result, the remaining Big Itch tests were conducted using only the smaller capacity E14.〔 Guinea pigs were used as test subjects and placed around a circular grid.〔Kirby, Reid.
