On A 6 Second G Force Pull The Pilot Passes Out, No Damage But to The Plane

 F-15 Eagle Costs $29.9 Million

Rob Verger

In late March of 2019, in a military operating area over Oregon, a student pilot and an instructor were conducting a two-aircraft training mission on basic fighter maneuvers. Each aviator was in their own F-15C jet. It was early afternoon, and the aircraft was at about 18,000 feet. The student made a turn, and during that maneuver, began to experience G-forces. About six seconds into that turn, those Gs caused blood to travel downwards from the pilot’s head, and the student passed out.

Eleven seconds later, after waking up, the pilot began to recover by putting engines to idle, and pulling back on the control stick. It was the correct course of action, according to the Air Force, but that maneuver subjected the jet to more stress than it was structurally designed to withstand. It endured a phenomenon called "over G-pull.” The wings, tail, and fuselage were all seriously damaged by the incident, adding up to a cost of more than $2.5 million. The Air Force has still not decided precisely what to do with the aircraft. (F-15C models cost $29.9 million, in 1998 dollars.)

Both F-15s landed safely, and neither pilot involved in the mission was injured.

The incident highlights the extreme forces that fighter pilots must manage as they operate high-performance aircraft. The student experienced G-induced loss of consciousness or GLOC. The Air Force Safety Center carefully tracks how often pilots pass out, and in the last fiscal year—from October 1, 2018, to September 30, 2019—there were 12 incidents, a small increase from past years. The 10-year average, according to the Safety Center, is about seven GLOC incidents per year. A majority of them involved students, and the one in Oregon was the only event that caused damage. Five of the 12 took place in F-16s, while others occurred in trainer aircraft like the T-6 or T-38, and one in an F-22.

The mid-air incident, not previously publicly reported, is also an example of the type of event the public doesn’t routinely hear about because it didn’t result in a crash. Popular Science learned about the incident through inquiries to the Air Force Safety Center. (The Air Force Safety Center notes that all GLOC events are investigated and that it’s an area in which they want pilots to remain vigilant about understanding.)

Fighter pilots have two major tools at their disposal to prevent them from passing out. The first is a tight garment called the G-suit, which squeezes an aviator’s legs and abdomen using air pressure, like a blood-pressure cuff. It connects directly to the jet itself, so the aircraft automatically determines when to engage it, and how much pressure to employ, based on how many Gs the pilot is feeling. The second is a muscle and breathing exercise called the anti-G straining maneuver, or AGSM: a pilot will flex and strain muscles in the legs, abdomen, and glutes. Both the G-suit and the AGSM work together, keeping the blood in the pilot’s brain and core and preventing it from pooling down below.

Military pilots use these tools while performing maneuvers—such as hard turning—to ensure they stay conscious, and it’s very hard physical work. The goal, of course, is to avoid passing out. A pilot who succumbs may wake up to realize that everything is fine, but it can also lead to a crash or the type of incident that took place in Oregon. 

“All the training that they do, and all the anti-G-straining maneuvers, and all the equipment, is designed to prevent this from happening,” says Cheryl Lowry, a physician, expert in aerospace medicine, and a retired Air Force colonel.

But different factors can cause a pilot to experience a GLOC anyway: the pilot could do the AGSM incorrectly, the equipment could malfunction, or he or she could have a health or medical issue. Dehydration can increase an aviator’s chances of passing out, too. In this case, the Air Force says the cause of the GLOC in March was identified, but falls under “Privileged Safety Information” and is not releasable to the public. Another GLOC event in the same fiscal year occurred when the air hose that connects the pilot’s G-suit to the jet became disconnected.

Before maneuvers that will subject an aircraft and its crew to Gs, pilots complete a “G-awareness exercise”—a series of turns to test whether or not the machine, and people on board, can properly handle the stress. In the Oregon incident, the aircraft did indeed carry out the G-awareness exercise first. 

The mishap resulted in the creation of an Air Force Safety Investigation Board report.

“The safety system has gotten better, and it’s more automated,” Lowry says. In the past eight to 10 years, the Air Force has created a “trackable database” where events like GLOCs reside, she notes.

The incident in March, she says, highlights the perils of the job, even when not flying in combat.

“Despite good training, and good aircraft, and good procedures, things still happen,” she adds. “It’s a very dangerous line of work, and it’s important that we continue putting money and effort towards training and selecting the right people.”

A USAF Gay Serviceman Classified as Undesirable is Now Honorable

A 91-year-old veteran who was dismissed from the U.S. Air Force as "undesirable" in 1948 because he is gay has had that discharge status changed to "honorable." 
The move by the Air Force comes in response to a lawsuit filed in November by H. Edward Spires of Norwalk, Connecticut, who served from 1946 to 1948 as a chaplain's assistant, earning the rank of sergeant. 

Hubert Edward Spires, left, is seen in this handout photo taken when he was in the Air Force. Spires, 91, was discharged due to his sexual orientation in 1948 and has filed a lawsuit seeking to change his status so he can have a military burial.

Spires was forced out of the military in 1948 after an investigation into his sexual orientation. 
Spires' attorneys said he was originally denied the discharge upgrade after the repeal of the Don't Ask, Don't Tell policy in 2010 because the Air Force said his records had likely been lost in a 1973 fire.  
The Air Force Board for Correction of Military Records informed Spires on Friday that the honorable discharge had been approved by the Air Force Review Boards Agency. 
Spires' attorneys have said he is in poor health and would like a military funeral, which the upgrade makes possible. 
"The idea that this man of faith who served dutifully as a chaplain's assistant in the armed forces, who built a life and a career that has brought joy to those around him, would leave this earth considered undesirable in the eyes of his country, it's unthinkable," Spires' husband, David Rosenberg, said during a briefing on the case at the Yale Law School in November. 
Spires' case also was championed by U.S. Sen. Richard Blumenthal, D-Conn., who said Monday that the Air Force’s decision "corrects an incredible injustice."

Gay Hero who Came Out before end of DADT killed in Afghanistan

 Here is our hero Adrianna with her partner celebrating end of DADT
Adrianna Vorderbruggen, a major in the Air Force who is known as one of the first openly gay service members since "Don't Ask, Don't Tell" was repealed in 2011, was killed in action along with six of her fellow service members in Afghanistan on Monday.

She was on a security patrol on foot near Bagram Air Base when an explosive-laden motorbike rammed into the patrol and detonated. Aside from the six who were killed, three U.S. service members were injured in the attack according to U.S. Army Brig. General William Shoffner, head of public affairs at NATO's Resolute Support Base in the Afghan capital of Kabul.

Shoffner said the attack, which was the largest attack on foreign forces in Afghanistan since August, happened around 1:30 p.m. local time.

Major Vorderbruggen had served as a special agent with the Office of Special Investigations at a number of duty stations including McCord's Air Force Base in Washington and Joint Base Andrews in Maryland before joining her unit at Eglin Air Force Base. From Eglin Air Force Base, she was deployed to Afghanistan.

After learning that Vorderbruggen had been killed while serving her country, Military Families and Partners released the following statement and photo on Facebook:

Our friend Air Force Major Adrianna Vorderbruggen was killed in Afghanistan yesterday. Military families understand that...

Posted by Military Partners and Families Coalition on Tuesday, December 22, 2015
Vorderbruggen and her civilian wife, Heather Lamb, were married in June of 2012, and were raising a son who is not yet five.

Hours after the suicide bombing, several rockets hit an area of Kabul housing foreign embassies and government buildings. No casualties were immediately reported but a State Department official told CBS News that U.S. Embassy staff was told to shelter in place.

The Taliban took responsibility for the attacks.

The U.S. now has about 9,800 troops in Afghanistan, some of which are involved in counterterrorism missions. With NATO contributions, there are about 13,000 foreign troops in Afghanistan.


The victims included New York City Detective Joseph Lemm, a 15-year veteran of the NYPD who also volunteered in the U.S. Air National Guard and was on his third deployment to war zones.
"Detective Joseph Lemm epitomized the selflessness we can only strive for: putting his country and city first," New York Police Commissioner Bill Bratton said in a statement.
Local media in Statesboro, Georgia, identified a third victim as serviceman Chester McBride Jr., who was remembered by the principal of Statesboro High School as "a young man of high character with a great smile."
Serviceman Michael Anthony Cinco of Rio Grande Valley, Texas, was identified by local media as another victim.
Facebook postings identified others as Staff Sergeants Peter Taub, whose family lives in the Washington, D.C., area, and Louis Bonacasa from New York.
“My son, Chef Jon's brother, Staff Sargeant Peter Taub was one of six killed yesterday in Afghanistan,” wrote the owner of the Taub family sandwich shop in Washington. “The restaurant is closed for the rest of this week.”
Wrote Air Force member Jeffrey Behrman: “Joseph Lemm and Louis Bonacasa, I'm glad to have known you men, I'm glad I was able to buy you men a couple pints before you left for Afghanistan.”
The Taliban, which claimed responsibility for the strike, remains resilient 14 years after the start of U.S. military engagement in Afghanistan. It has ramped up its attacks this year, inflicting heavier casualties on Afghan security forces.
Just last week, the Pentagon warned of deteriorating security in Afghanistan and assessed the performance of Afghan security forces as "uneven and mixed."
More than 2,300 U.S. troops have died in the Afghan war since the 2001 invasion, but the pace of U.S. deaths has fallen off sharply since the end of formal U.S. combat and a drawdown of American forces.
Pentagon data showed there have been 10 so-called "hostile" deaths of U.S. service members in Afghanistan this year. There have been 10 non-hostile deaths, largely from aircraft crashes. (Reuters)

Rachel Maddow Unleashes Her Anger at USAF (ex-gay) Cadet-Counselor Head

Out MSNBC anchor Rachel Maddow filed an impressively in-depth report on the state of the GOP's current antigay animus on hereponymous show last night
Maddow opened by taking to task the U.S. Air Force, which recently confirmed that the man leading its mandatory cadet counseling program has spent the past two decades of his career advocating the scientifically debunked, harmful process of "ex-gay" or "reparative therapy." Our colleagues at sibling site The Advocate reported on those allegations yesterday, first broken byAmericaBlog's John Aravosis. 
"What were they thinking in hiring this guy?" asks Maddow, incredulous. "Did the Air Force hire him despite this area of expertise, or did they hire him because this is actually what they wanted?"
In uncovering Dr. Mike Rosebush's professional background, Maddow notes that the antigay scientist authored at least two books on how to rid oneself of "unwanted homosexual desires." One of those, a "handbook" for "overcoming" a gay or lesbian sexual orientation, was co-authored by disgraced researcher and former board member of the National Association for the Research and Therapy of Homosexuality, George Rekers. You might recall his name from the infamous "RentBoy" scandal, when the leading proponent of therapy that supposedly turns gay people straight was found returning from a European trip with a young, handsome call boy. Rekers claimed he hired the strapping young lad from to "carry his luggage," but the young man contended that Rekers instead requested intimate massages. 
Maddow then turns her attention to the "Radically antigay politics [that] are in ascendance in the Republican party." Touching on the very public feud between the Cheney family over marriage equality. 
Next, Maddow reports on yesterday's decision from the Texas National Guard that it will continue to defy direct orders from the Pentagon ordering all Guard units to extend spousal benefits to the partners of legally married gay and lesbian soldiers. 
"In Texas, the political calculation is that it is more important to be antigay than to support the troops."
But ending on a positive note, Maddow sits down with Illinois governor Pat Quinn, who is scheduled to sign marriage equality legislation into law this afternoon.

F-22 Phantom Jet To Iranians Pilots in Pursuit of US Drone "you really ought to go Home" [They Did]

The U.S. Air Force has a message for Iran: Don’t mess with our drones.
 The Aviationist reports that in March a U.S. MQ-1 drone came close to being intercepted by an Iranian F-4 Phantom combat plane, but the Iranian aircraft stopped short after a warning by an American pilot.

In what only can be described as a scene out of Tom Cruise’s “Top Gun,” Gen. Mark A. Welsh IIIAir Force chief of staff, describes how F-22 stealth jets scared off Iranian jets from 
a U.S. drone flying in international airspace.

“He [the Raptor pilot] flew under their aircraft [the F-4s] to check out their weapons load without them knowing that he was there, and then pulled up on their left wing and then called them and said ‘you really ought to go’” Gen. Welsh said.

According to The Aviationist, the Iranians came within 16 miles of the drone.
