The mission plan for the second attack was nearly identical to that of the Hiroshima mission, with two B - 29s flying an hour ahead as weather scouts and two additional B - 29s in Sweeney's flight for instrumentation and photographic support of the mission . Sweeney took off with his weapon already armed but with the electrical safety plugs still engaged . </P>
