Just came across this little gem....
The following is an ATC strip assigned to the C-130.

Notice the "TL270" on the strip. That is a heading
vector. Why would ATC note a heading
vector if the Camp Springs One was assigned for departure and the Camp Springs already calls for 270 heading? Answer is, they wouldnt, they would only note a vector if assigned a departure which calls for vectors, The Morningside One.
So, lets recap.
ANC witnesses place the C-130 approaching from the NW. O'Brien claims he passed "south of the mall" (not south of DCA), and the ATC strip notes a vector.
Camp Springs was
not assigned to Gopher06 (for obvious reason explained ad nauseum on this forum, eg. morning rush hour into DCA). The govt story and those who make excuse for it have imploded once again. No wonder they wish to remain anonymous and create new internet userID's when their old ones are fully discredited.
(also note the 1333 in the lower right, i believe that is the wheels off time, several to many minutes after the national ground stop depending on which source you believe, Spencer or the State Dept)
