I work near 95 in Beltsville, practically 20 miles away, and from my 15th floor office window I could see the huge cloud of smoke. For a couple minutes I was convinced a plane had crashed en route to BWI.

Yeah, that's what we thought initially, especially since the explosion was heard by those outside. It was about 4 miles away from us, but it looked more like 2 miles from the smoke.
