Just checked FlightRadar24 and noticed that Icelandair 630 from Boston to Reykjavik turned around a few minutes after takeoff. I checked the squawk code and it looks normal. I’m listening to the approach and tower ATC via liveatc.net. Updates will follow below.
Update (11:02PM EDT): ICE630 has landed safely on 33L parked at gate E3A. No word on what the situation was but I will keep an eye on local news or airport info.
