Best Bond movie mistakes of 1967

Plot hole: Right after Bond escapes Blofeld and joins Tanaka and Kissy, they say they need to get to the Control Room (that Bond just left from), they look at the "front door" to the Control Room and Tanaka says "Impossible! It's too well defended!". Why did they not go back the way Bond just came from, through Blofeld's "apartment"? Instead, they fight their way across the entire launching complex and go through another entrance, which ALSO leads through Blofeld's "apartment".
