counber ed, One was that nssembly ar eas chosen were too 010'19 together,resulting in some aircraft of the 313th Wing mcking assembly with thoseof the 3l4th Wing and thereby bombing the 314th Wing's aiming point.Formation. aCross the target varied from 5 to 16 aircraft. Smoke ob-scured aiming pOints nfter the first 2. or 3 formations bad dropped theirloads, and lead bombardiers who rollo~d resorted to bombing by ~fer.ence points, a procedure which sCattered bombs. Subsequent reconnaissancephotographs showed many concentrnted patterns in the target area (Seostrike attack photograph in Part III, Annex D, of this report). O n esquadron of the 314th Wing ba d n premnture release, when a wing bombar-dier aCCidently hit the toggle ~itch when under fighter nttnck. Thispattern was about 5000 feat short of aiming point. One squadron o t the3l3th Wing also hnd 0. premnture relense, but this wal close snough totho target nreo. for mnny of the bombs to hit fnctory installation Twelve o.irplo.nes reported that bomb bay doors failed to open or close.On future missions it is planned to have group assemb1~o. near [wo Jlmaa nd W in g' n es e mb l y at n point $ Om eW ne EQ b Ot we en , this point'and the oo~t ofilGptl.ll. all 1~1l.lo.!W" are b ein g eq uip ped wlnh smolte gOnGl'atot. to aid in.t ro up a ss em bl y.
