Could it be related to EW (Electronic Warfare) activity?
Here is a
picture of strange radar activity that is theorized as EW but one thing is
certain....these aren't natural patterns. There was another thread about something similar to
this....
here.
The fact that this is over DC is what bothers me. If it is related to electronic warfare, is it eminating from DC or is it targeting DC? EW can
cause things like earthquakes and severe weather, which don't necessarily show up right away. And it can disrupt electronic equipment although I
would think this would be immediate.
