What is not apparent in the photos are the thousands of people witnessing the event from the ramp. Aircraft will be down for a while, but at least those guys are ok...

Fighter Jets Plagued by Problem With Brakes, Records Indicate
By THE ASSOCIATED PRESS
Published: August 7, 2005
WASHINGTON, Aug. 6 (AP) - The front-line fighter jet of the Navy and Marines has suffered a series of accidents suspected of being caused by brake failure, and the problem has spurred warnings from commanders, documents obtained by The Associated Press show.
Brake problems affecting the jet, the F/A-18 Hornet, pose "a severe hazard to naval aviation" that could kill pilots and ruin valuable aircraft, a Navy air wing commander wrote last year after one of the jets roared off a runway and into San Diego Bay, destroying the $30 million plane.
Many of the brake failures have been traced to a $535 electrical cable - about as thin as a drinking straw - that controls the jet's antiskid brakes, the equivalent of antilock brakes on a car. Investigators say the cable can chafe or break, since it is close to where tie-down chains secure the jets to a carrier deck.
In the crash in San Diego, Navy investigators cited "a trend of similar, if not identical, emergencies" dating to 1990 that had gone unnoticed until several failures last year, according to records obtained by The A.P. under the Freedom of Information Act.
One Navy pilot aborted a landing last fall when his brakes failed after a combat mission over Iraq. He took off again, circled the runway in Kuwait for a second landing attempt, then lowered his tail hook and caught the emergency arresting cable on the ground. He was not hurt and there was no damage to the jet, the records showed.
A month earlier, a Marine commander was seriously injured when he ejected after the jet's brakes failed while he was landing on a short runway at Marine Corps headquarters in Quantico, Va.
The Navy ordered fleetwide inspections last fall and is continuing to investigate whether the brakes need to be redesigned, as some commanders have urged. "This matter is by no means closed," said a Navy spokesman, James Darcy.
The maker of the jet, Boeing, deferred comment to the Navy.
The military owns 561 Hornets, including those flown by the Blue Angels aerobatic team. They are a mainstay of Navy and Marine aviation, and they flew more than 50,000 sorties at the height of fighting in Afghanistan and Iraq.
Upon request, the Naval Safety Center in Norfolk, Va., located about two dozen formal reports describing failures of the Hornet's antiskid brakes since 1990. The incidents resulted in the loss of one jet, damage of at least $1 million to another and one serious injury.
Officials acknowledge that their tally of formal reports probably understates the number of failures. A report filed in January referred to 14 Hornet brake failures and tire blowouts in one squadron in 2004.
"This trend of brake failures and blown tires cannot be ignored," Marine Col. Earl S. Wederbrook wrote to senior Navy and Marine officials after one jet spun backward on a runway from a blown tire in California.
The Navy said the antiskid brakes were reliable, and that pilots should be able to land safely despite problems if they follow proper emergency procedures. It also said the sporadic brake failures must be viewed in light of the jets' roughly six million landings since the 1980's.
the truth: first it is ridiculed second it is violently opposed finally it is accepted as self-evident
