Hi everyone, Hope someone can help me. The GBU38 dropped in VIS Mode miss the Target by several hundret Feets, everytime. Used Hot start from the Ground and GBU allingnement was at RDY state. Flight Time only about 5mins, could this be an Error with INS allignement? Drop Cue was in Range off corse, tried different distances, Bombs hit the Ground pretty accurate but far away from Target. Speed about 350 KIAS Thanks in Advance Chervo
