MC1 ?

When I track activity around my home airport (CYFB, Iqaluit, Nunavut, Canada) I sometimes see flights which show a departure airport MC1 which appears to be in Europe, and a destination in California/Idaho etc). The aircraft are generally US registered, single engine (C172/C182/AA5/RV-7 etc). As I write this, I can see 5 of these flights that appear to be currently over Baffin Island in the Canadian Arctic, on 12 or 13 hour flights from Europe. Must have some monster ferry tanks :slight_smile:

When I click on MC1 for info, it says it isn’t in the Flightaware database.

Anyone know why Flightaware seems to place these phantom small planes over the Arctic?
