While we see a German-registered Goodyear Zeppelin "blimp" fly over London today, surely not a reaction to the football result (?), I'd always thought they were American-registered so I looked them up on the FAA website. How on earth did Goodyear manage to get N1A, N2A, N3A and N4A, an awful lot of money I presume? Screenshot courtesy FlightRadar24.
