The other thing I picked up on is the frequency of these military helicopter flights in and out of Washington DC? Apparently the military is running personalized air taxi service to key government officials, taking them to or home from their offices. This also needs to be explained. What were they doing cutting thru an ILS approach glideslope localizer inside of the inner marker beacon? What was the purpose of their mission, and previous missions?
Were they running a VIP air taxi service?
Word is it was a night fly training op.
