Just notice this Dutch Air Force MRTT doing a touch and go at Shannon before heading out over the Atlantic https://globe.adsbexchange.com/?icao=480c40&lat=53.726&lon=-10.025&zoom=7.3&showTrace=2020-10-09 ?? Clearing US Customs
Did that... she didn't stop. Also I was watching the aircraft at the time as up-dating my Basestation DB on VRS at the time. She now appears to be heading for Iceland, so most likey not clearing US customs.
