From IPN:
“MAS| Boston| Airport Alert| | Logan International Airport|Airport has been directly struck by lighting and is now closed [MAS198]| IND041| 16:59”
It’s a good time to be watching for diversions.
Here’s one: flightaware.com/live/flight/BTA1232
Edit: I see this has actually landed, probably before the lightning strike.
So here’s another: flightaware.com/live/flight/TRS222
I saw those strikes while I was moving (no, I don’t recommend moving during a thunderstorm) into my new apartment (about 2 miles from the airport) today.
