Marine investigators say an F-35B stealth fighter pilot grew disoriented amid multiple system failures while flying in stormy weather over North Charleston in 2023, prompting the pilot to eject even though the jet was still capable of flying.
Investigators identified an "electrical event" during the flight that triggered multiple malfunctions, including the aircraft's radios, transponder and air navigation system.
Glitches also caused the plane's $400,000 helmet-mounted display to flicker at least three times.
But the investigation concluded that the pilot's decision to bail out of the jet was "ultimately inappropriate" because other instrumentation was "partially operational." As proof, the report said: "Furthermore, the aircraft continued to fly for an extended period after ejection."
The Marine Corps report redacted the pilot's name, but a Defense News story Oct. 31 identified him as Col. Charles "Tre" Del Pizzo, 49.
The Marine investigative report said no punitive actions were taken against the pilot. However, Defense News quoted Del Pizzo as saying he recently lost command of a squadron in Arizona because of the mishap.
The report comes more than a year after two Beaufort-based F-35Bs were flying near thunderstorms over Charleston International Airport. Under these dark clouds, one pilot ejected. But his F-35B kept flying.
Search parties deployed across the region, hunting for a crash site. The situation grew more bizarre as time passed without any evidence of a crash. Social media memes spread, including one with an F-35 on a milk carton and the word “Missing” splashed across it.
About 27 hours later, search crews finally found the wreckage. Debris was strewn across a field and swamp in the Indiantown community in rural Williamsburg County, about 64 miles from North Charleston. The crash had burned patches of pines brown and scattered fragments across a cotton field.
Military cleanup units arrived, erected signs declaring the area a national defense zone and excavated a crater big enough to hold a couple of trucks.
Then, more than a year passed without any word about what caused the ejection, a delay that raised eyebrows. The Marine Corps normally issues a preliminary report within a few months, Dan Grazier, a defense expert with the Stimson Center think tank, told The Post and Courier earlier this year.
“The longer (the investigation) drags out and we don’t hear about the findings, the more suspicious it gets that there’s some systemic problem with the aircraft,” he said.
The Marine investigation ultimately found a combination of system and pilot errors led to the ejection and crash.
Details of F-35B ejection
In its investigation, the Marine Corps said the Beaufort-based pilots knew the weather might be bad over Charleston the afternoon of Sept. 17, 2023, but forecasters predicted at least four miles of visibility, so the mission went forward.
But the weather soon grew worse, with lightning detected within 10 miles of Joint Base Charleston. The two pilots completed their training mission and planned to land at the Charleston base. One landed, but the second ran into trouble.
The F-35B is capable of hovering, and as the pilot neared the base, he pressed a button that converts the aircraft from conventional flight to hover mode.
A minute later, displays began to malfunction, the Marine report found. The pilot (identified by Defense News as Col. Del Pizzo) raised his landing gear and put the plane back into its non-hover mode.
In an interview with investigators, the pilot said his helmet-mounted display flickered. The display allows pilots to see through the jet's gray skin, thanks to six external infrared cameras on the plane. It also is the pilot's critical link to flight and tactical sensors.
The pilot said he saw multiple malfunctions on his helmet display, and that he thought the jet might have an engine problem. He lost contact with air traffic controllers. He saw more failures.
"Unsure of which instruments he could trust, (the pilot) perceived he had entered out-of-control flight."
The pilot then "ejected from a flyable aircraft, albeit during a heavy rainstorm compounded with aircraft electrical and display malfunctions," investigators later concluded.
Ejection and crash details
The Marines offered somewhat conflicting details about his experience.
One section of the report described him as a "highly experienced fighter/attack pilot" and an instructor VMFAT-501 in Beaufort. Yet, he also was "relative novice in the F-35B." Another section noted that the pilot had more than 1,200 flight hours on the F-35 before the mishap.
Del Pizzo's official Marine Corps biography said he is from Atlanta and completed his Marine Corps Parris Island training in 1993. He was deployed six times, including roles in Operation Enduring Freedom in Afghanistan, the Second Gulf War and Operation Inherent Resolve, the international war against the Islamic State. He had more than 3,000 hours in multiple military and civilian aircraft.
Ejecting from a fighter jet is a lesson in violence. A line of explosives blows off the canopy. Straps pin a pilot's arms and legs to the seat. Air bags inflate around the pilot's neck and head. A rocket fires, launching the pilot into the air, a process that generates as much as 18 Gs.
During Del Pizzo's ejection, the force ripped off his helmet and mask. The pilot saw he was floating into a residential neighborhood and used his steering toggles to avoid power lines and land in a backyard. A resident helped him into the kitchen and called 911.
The Post and Courier obtained a recording of that call.
“… I guess we got a pilot in our house, and he says he got ejected, or he ejected from the plane,” the resident told the dispatcher. “So can we just see if we can get an ambulance please?”
“I’m sorry, what happened?” the dispatcher said.
Del Pizzo took the phone.
“I’m the pilot. We need to get rescue rolling. I’m not sure where the airplane is. It would have crash-landed somewhere. I ejected.”
Del Pizzo said he was OK but that his back hurt. The dispatcher asked, "OK, and what caused the fall?"
“An aircraft failure,” Del Pizzo answered.
After paramedics arrived, Del Pizzo walked to the ambulance and was taken to the Medical University of South Carolina.
Above, his plane traced an unusual route.
It flew "in a nominally trimmed condition" for 11 minutes and 21 seconds, climbing at a 10-degree angle to about 9,300 feet, then descending in a right turn.
The jet then began "clipping the top of a densely forested area," the report found.
The investigation concludes the jet was able to continue flying due to its "advanced automatic flight-control systems."
The report said Air Force personnel in Charleston lost contact with the plane near Bonneau, about 25 miles north of the base.
Marine investigators offered several reasons for the 27-hour delay in finding the wreckage: the loss of radar contact; its flight below air traffic control's radar horizon; and its stealth technology.
More questions
Investigators cleared the pilot of dereliction of duty. Del Pizzo assumed command of a squadron in Yuma, Arizona, in June, months after investigators had done much of its investigation.
But on Oct. 2, Marine Corps Lt. Gen. Bradford Gering relieved Del Pizzo of his command in Yuma, Defense News reported. Gering reportedly cited a "loss of trust and confidence in his ability to execute the responsibilities of his command.”
The Post and Courier could not immediately reach Del Pizzo for comment.
The report comes against a background of air space successes and questions about the jet's reliability.
Together, the three F-35 variants make up the nation’s most expensive weapons program and among the most important. It's known as a fifth generation fighter, meaning it was designed to replace stalwarts such as the F-16 and F-18 fighters.
The Marines said the plane's loss amounted to $100 million, but other cost data suggest a higher price tag of about $150 million apiece, including all necessary and supplies.
The ejection and crash in South Carolina follow at least 10 other F-35 crashes since 2018 and come amid longstanding questions about mounting costs, which may pass the $2 trillion mark for the whole program, according to one recent federal report.
For nearly four years, the Air Force limited certain F-35s from flying near thunderstorms over fears that lightning could cause the fuel system to explode.
Inadequate training and the lack of spare parts also have been chronic problems. The U.S. fleet of F-35s has failed its readiness goals for the past six years, the Government Accountability Office said in an Oct. 21, 2024, analysis.
At the same time, F-35s are being used increasingly in combat operations, including Israel's recent attack against Iran.
