The stop at Bellingham airport is only needed because of the required American CIQ. After advance contact by the FSI and a short phone call by us in the morning everything is prepared. We have to park on the designated customs parking bay in Billingham. A friendly officer CBP welcomes us in German language. The process thereafter is completed very quickly. We let fill up our wing tanks and only a little more than two hours we are back in the air heading California.
