Tibbets, in a 1994 interview aired during the Smithsonian Networks program Smithsonian Channel's War Stories (1995, "The Men Who Brought the Dawn"), stated that a third bomb was available "at Wendover" and that "the bomb" had been transported as far as Mather Field when further missions were cancelled. However, since plutonium cores and initiators were transported separately by courier from Los Alamos, it is likely that if any part of a bomb had been en route, it was only a bomb pre-assembly, possibly to have a second in place in addition to F32 and thus permit a rehearsal before any third mission. Sources familiar with Groves state categorically that even though physicist Robert F. Bacher had signed for receipt of the core and initiator, the order to halt shipment reached Los Alamos before the pit left the site. Lawren 1988, p. 253; Campbell 2005, p. 39 Lawren, William (1988).
