An ATR-72, reg G-CMJN, identifying with callsigns like EAG001T (on ADS-B) and "Greenstone 1 Tango" (voice with ATC) has been back and forth between EGAC and EGAE several (I think three) times a day for the last three days. This appears to be the UK arm of Emerald Airlines. Anyone know what these flights are about? They don't appear on the City of Derry live flight info web page (where other commercial flights do).
