Over the top and then the explosion, that is the purpose of the loop, it's size was what was needed to synchronize the fly-over and the explosion.
Most eye-witnesses followed the plane until the explosion. If the explosion happened after the plane went over the top wouldn't that be apparent to an onlooker?
At the very least, someone would have said that the plane went over the Pentagon and then blew up
if there was a fly over it seems it was the C-130 that is hardly mentioned in any of the witness testimony still in circulation...but it was there and admitted flying over the pentagon after the impact of "the plane"... that`s the official account anyway....or was it the decoy flight path that provided the radar reading and flew over while the "plane" hit..then covered up by a few minutes changed in the timeline and a dive by?...could be..here are some witness testimony about the C-130...
"The image of a jet slamming into the side of the Pentagon continues to haunt Pam Young and Keith Wheelhouse. The brother and sister had just finished burying her brother-in-law at Arlington National Cemetery when they witnessed the final seconds of American Airlines flight 77.
Perhaps more remarkable is her insistence that a second plane was flying near and along the same path as the hijacked jet. Her brother, Wheelhouse, of Virginia Beach, spotted the planes first.
The second plane looked similar to a C-130 transport plane, he said. He believes it flew directly above the American Airlines jet, as if to prevent two planes from appearing on radar - while at the same time - guiding the jet toward the Pentagon."...Disaster Viewed From Arlington by Terry Scanlon, Daily Press September 14, 2001.
"Planes never pass over her Fairfax County apartment, she said, so when a low-flying, high-speed plane buzzed the high-rise, she jumped up, ran to the windows and saw the rear of a jet heading toward Washington, D.C. A few seconds later, a second plane that seemed to be chasing the first passed over at a slightly different angle, she said.
"Thank God somebody else saw that. There was most definitely a second plane," Knowles said. "It's so frustrating because nobody knows about the second plane, or if they do they're hiding it for some reason."
Hampton Roads Woman Says She Too, Saw Plane Following Jet That Hit Pentagon by Terry Scanlon, Daily Press, September 15, 2001
My [Scott P. Cook] office is located on the fifth floor of the Portals building, at 1280 Maryland Avenue SW, Washington DC. It's the southernmost building at the end of 14th Street, right at the Tidal Basin and Maine Avenue.[...] As we watched the black plume gather strength, less than a minute after the explosion, we saw an odd sight that no one else has yet commented on. Directly in back of the plume, which would place it almost due west from our office, a four-engine propeller plane, which Ray later said resembled a C-130, started a steep decent [sic] towards the Pentagon. Cloth Monkey, September 2001
Northern Virginia resident John O'Keefe was one of the many commuters who witnessed the attack on the Pentagon. [...] "The first thing I did was pull over onto the shoulder, and when I got out of the car I saw another plane flying over my head, and it scared ...me, because I knew there had been two planes that hit the World Trade Center. And I started jogging up the ramp to get as far away as possible. "Then the plane -- it looked like a C-130 cargo plane -- started turning away from the Pentagon, it did a complete turnaround. New York Lawyer, September 12, 2001
"The fireball that erupted upon impact blossomed skyward, and the blast hit us in a wave. [...] Then a gray C-130 flew overhead, setting off a new round of panic. I tried to reassure people that the plane was not a threat. All around me people began to panic, fleeing for their lives." militarycity.com/sept11/911_1068139.html, September 2002
C-130 witness, Allen Cleveland: My brother inlaw also witnessed the same [C-130] following the jet while he was on the HOV lanes in Springfield. He said that he saw a jetliner flying low over the tree tops near Seminary RD in Springfield, VA. and soon afterwards a military plane was seen flying right behind it.
Here`s the pilots view of events on the one year anniversary, notice he confirms he was at both flight 77 and flight 93 official crash sites as the confirming eye witness.......
"Lt. Col. Steve O'Brien started his day at the controls of a Minnesota [Air] National Guard C-130 cargo plane. He and his crew were heading back to the Twin Cities after moving military supplies around the Caribbean. About 9:30 a.m., O'Brien throttled the lumbering plane down a runway at Andrews Air Force Base, just southeast of the District of Columbia.
"When we took off, we headed north and west and had a beautiful view of the Mall," he said. "I noticed this airplane up and to the left of us, at 10 o'clock. He was descending to our altitude, four miles away or so. That's awful close, so I was surprised he wasn't calling out to us.
"It was like coming up to an intersection. When air traffic control asked me if we had him in sight, I told him that was an understatement - by then, he had pretty much filled our windscreen. Then he made a pretty aggressive turn so he was moving right in front of us, a mile and a half, two miles away. I said we had him in sight, then the controller asked me what kind of plane it was.
"That caught us up, because normally they have all that information. The controller didn't seem to know anything."
O'Brien reported that the plane was either a 757 or 767 and its silver fuselage meant it was probably an American Airlines jet. "They told us to turn and follow that aircraft - in 20-plus years of flying, I've never been asked to do something like that. With all of the East Coast haze, I had a hard time picking him out.
"The next thing I saw was the fireball. It was huge. I told Washington the airplane has impacted the ground. Shook everyone up pretty good. I told them the approximate location was close to the Potomac. I figured he'd had some in-flight emergency and was trying to get back on the ground to Washington National. Suddenly, I could see the outline of the Pentagon. It was horrible. I told Washington this thing has impacted the west side of the Pentagon."
O'Brien asked the controller whether he should set up a low orbit around the building but was told to get out of the area as quickly as possible. "I took the plane once through the plume of smoke and thought if this was a terrorist attack, it probably wasn't a good idea to be flying through that plume." [!]
He flew west, not exactly sure where he was supposed to land. [!]
Somewhere over western Pennsylvania, O'Brien looked down at a blackened, smoldering field. "I hoped it was just a tire fire or something, but when I checked with Cleveland center, he told me he'd just lost a guy off the scope pretty close to where we saw it. By then, we were able to patch in AM radio, so we heard about all the planes. It was like a domino effect - a really bad day for airplanes." Minnesota Star-Tribune, September 11, 2002
i think the C-130 holds alot of answers, which is probably why it hardly gets mentioned..
