The group of aircraft would pass through Polish airspace for no more than a few minutes on their way to northern Germany. At the moment they were well within the zone watched by both German and Polish air-search radars, but those were not a concern. The mission's planners were more worried about accidentally crossing paths with an air patrol or a routine transport from the German port and military base at Bergen. Their flight path would take them across the northwest corner of Poland, about a hundred kilometers from that base.
