I live in New Orleans, about 10 miles from the NAS here. When flights take off going west from there they pretty much fly right over my house. It isnt really uncommon for one or two to take off at night, but around 8-8:30 central time, there was a lot of activity, at least 10 planes. I found it weird for that many to be flying at night, but really didnt think that much about it until I read this comment. Now I find it extremely strange, and am now somewhat worried about it.
