father-in-law, that he was able to get off of the train. there was an overhead announcement, emergency announcement, telling everyone they had to get off the train and to go up the escalator, go upstairs, and now people who were in the airport at the time of the shooting are in the holding situation where they are just hanging around, trying to get more information. as you might imagine, the airport staff doesn't want to alarm anyone so they're really not giving them a lot of details. most of the passengers, people who have just landed or they're trying to connect to a different flight, are learning information piece by piece through social media and different news outlets because they say they're not getting much information from the airport at all. so that's what i'm learning from people who are inside. my own family members are in the airport right now, who are trying to figure out what's going on and how they can get out. there are concerns, because this is such a large airport and this is such a busy travel season
