>Af1 left G7 on 6.9 and Whidbey missle 6.10
AFAIK a Trident is a ballistic missile, not anti-aircraft. Trident target may have been somewhere that could then be blamed on NK; like Japan, e.g. If so, date of landing would have been planned to disrupt summit. IOW, AF1 location not relevant because AF1 wasn't the target.
