Because US$40 billion was apparently not enough to avoid problems that did not affect cold war era airplanes.

Likely contamination of ground handling equipment [1]. Unfortunately can happen. I wonder if the hydraulic fluid is hygroscopic or something?

1. https://www.pacaf.af.mil/Portals/6/documents/3_AIB%20Report....

4gotunameagain•1h ago
Hydraulic brake fluid is glycol ether based and hygroscopic. Planes usually use mineral based fluids which are not, but heck if I know what the F-35 uses.
grumpy-de-sre•1h ago
Quoting ChatGPT (and after a quick sanity check),

The F-35 Joint Strike Fighter uses a specialized hydraulic fluid that’s based on a synthetic ester formulation, not a petroleum-based fluid.

Specifically, it uses phosphate ester–based fire-resistant hydraulic fluid (commonly in the MIL-PRF-83282 or newer MIL-PRF-87257 class).

Apparently the older phosphate-ester based hydraulic fluids were hygroscopic but I'm not sure if the newer variants are.

yobbo•1h ago
Sounds similar to DOT-5 brake fluid.

Maybe this: https://en.wikipedia.org/wiki/Tributyl_phosphate

"The major uses of TBP in industry are as a component of aircraft hydraulic fluid, brake fluid, and as a solvent for extraction and purification of rare-earth metals from their ores"

It might be better if it is hygroscopic as the water won't separate and risk forming ice plugs in the hydraulic lines.

Who eats the loss under such circumstances?

Government or Lockheed Martin or are these 200 million dollar jets insured ?

nelox•1h ago
Self-insured. The government absorbs losses itself instead of purchasing commercial insurance.
zrail•1h ago
Ultimately the US taxpayers will eat the loss in either case. If the government tried to charge it back to Lockheed Martin they'd just raise the price on subsequent programs to compensate.

The government does insure weapons of war. Who would write the policy?

bedane•1h ago
is insurance for military equipment a thing? I had no idea.

If you have very deep pockets like a nation has, why not simply replace the lost hardware and never insure/pay premiums(which would be calculated to net a profit to the insurer)?

meindnoch•1h ago
Where did they get this 200million figure from? Sounds bogus.
dgacmu•6m ago
The per plane cost varies a lot depending on what you want to wrap in it: how much of the development costs you amortize, the modernization program, etc. but $200m is in the range.

("Total acquisition costs" vs the marginal cost of the next plane can result in a more than 2x difference in how much you think the plane costs)

The flyaway cost of buying one more plane is probably a bit under $100m though.

ux266478•5m ago
F-14D unit cost was ~$74 million in 1988. Adjusting for inflation that's ~$202 million in 2025. It's not that unreasonable for an American fighter jet, honestly.

> "they likely would have advised a planned full stop landing or a controlled ejection instead of a second touch-and-go"

Is that not what the pilot did anyway? Or is a "controlled ejection" different from what they did?

the_real_cher•1h ago
I had the exact same thought.
fabian2k•1h ago
The article mentioned that the aircraft become uncontrollable once it thought it was on the ground and switched control modes. And then the pilot ejected.

I assume a controlled ejection would have been during controlled flight at a time and location specifically chosen. This ejection was necessary because the plane was uncontrollable in the end.

voidUpdate•1h ago
Ah, I see, ejection in a controlled situation instead of "oh no, time to go now"
lentil_soup•1h ago
If I understood correctly, the ejection came after the second touch and go made the plane go into landed mode which made it impossible to fly anymore
freefaler•1h ago
So as a pilot you can't override the software to stop it from "thinking that the plane is on the ground" mode?

Something similar happened recently with A320 when it didn't want to land on an airfield during emergency unless it was flown in a special mode. But F-35 doesn't have that?

netsharc•25m ago
> unless it was flown in a special mode.

What fresh hell is that... reboot, jam F8 just as the "Airbus" logo shows up, and then select "Boot in safe mode"?

xattt•13m ago
Fly-by-wire aircraft have changeable “flight laws” that correspond to different levels of computer intervention to mitigate situations incompatible with controlled flight.

Think of it as various stability control modes in a modern car. Likely the aircraft needed to be put in the least restrictive flight law mode as a workaround.

crote•3m ago
Airbus is fully fly-by-wire. Without some kind of computer intervention, nothing would be stopping an accidental bang against the flight stick from causing a maneuver violent enough to rip the wings off.

An Airbus can operate in three modes. With Normal Law, the airplane will refuse to do anything which will stop it from flying. This means the pilot cannot stall the airplane, for example: the computer will automatically correct for it.

With Alternate Law the pilot loses most protections, but the plane will still try to protect against self-destruction. The plane no longer protects against being stalled, but it won't let you rip the wings off.

With Direct Law all bets are off. Controls now map one-to-one to control surfaces, the plane will make no attempt to correct you. All kinds of automatic trimming are lost, you are now essentially flying a Cessna again. The upside is that it no longer relies on potentially broken sensors either: raising the gear while on the ground is usually a really stupid idea - until the "is the plane on the ground" sensors break.

So no, a "Boot in safe mode" isn't as strange as it might sound at first glance. It significantly improves safety during day-to-day operations, while still providing a fallback mechanism during emergencies.

seethishat•15m ago
"On the ground" = WoW sensors. WoW sensors have been around a long time (see link). And, humans probably should not have any say about that. If humans could override WoW, then the landing gear could be deployed or retracted when it should not and cause a lot of damage due to human error.

https://en.wikipedia.org/wiki/ACARS

jcalvinowens•6m ago
I know the 737 allows the pilot to override that (force the wheels to raise even if the airplane thinks it's on the ground). I think most airliners do. I can't find a good succinct reference though.

EDIT: Remembered Airbus exists

gherkinnn•1h ago
The F35 has been a shit show for 15 years or more. So not only is it a disaster at the tactical and operational level, with the US holding the keys and being run by a cretin, it is now also a strategic blunder.

The French were right with their strategic autonomy, de Gaulle evidently prescient, and the various EU countries falling for the F35 would have been better off choosing the Rafale or Gripen.

luma•1h ago
That is a patently absurd take, ask Iran how much of a shitshow it is to be on the receiving end of planes your AA can't see.
gherkinnn•1h ago
The B2 is what did the damage in Iran. F22 and F35 were reportedly sent to protect the bombers.

I don't see how that detracts from the point that the F35 has been fraught with problems and operating it is dependent on an unreliably ally.

hollerith•1h ago
Israel has no B2s. Israeli F35s flew constantly over Western and Central Iran (including Tehran) for 12 days as if Iran's extensive air-defense network was not even there, doing a lot of damage.

Russian milbloggers responded with, "Why can't the Russian air force fly over Ukraine like that?"

UltraSane•16m ago
This is completely wrong. B2 bombers only dropped the MOAB on the nuclear enrichment sites. Israel used F35s to bomb Iran at will. Iran didn't shoot down a single plane.
etempleton•25m ago
The F35 program had a ton of issues and was expensive, but so was the B2 program. Sometimes something good comes out of a difficult process. They have made a lot of F35s now and exported many of them with many many more on order. At this point I think it is fair to say the F35 is a successful platform.
UltraSane•17m ago
Ask Iran how much of a shit show the F35 is.
Molitor5901•1h ago
Considering they relieved a pilot of command for ejecting when his F-35 become unresponsive, now they make them sit on conference calls. That pilot is very brave, I think others would have ejected by now. Making them fly around up there is ridiculous.
5f3cfa1a•19m ago
Ejecting from an airplane is no joke: 18g of force leaves 20-30% with spinal fractures, and ejection seats have an 8% mortality rate[1]

It seems to me that continuing flight with inoperative/damaged landing gear while you discuss alternatives with engineers is the safest option. Burn fuel, make a plan, let people on the ground mobilize to help, and eject when you've tried what you can and it truly becomes the safest option.

RankingMember•12m ago
Upon first reading the headline I was thinking it was some sort of test flight. Nope, poor guy was just trying to fly and ended up forced into a high-stakes troubleshooting tree while on a conference call, as if there's not enough on your mind in a fighter cockpit.

I don't know how many human-manned gens of aircraft are left, but my first inclination is to think a remote-control fallback option wouldn't be out of line here if the security could be done right.

Aurornis•7m ago
> That pilot is very brave, I think others would have ejected by now. Making them fly around up there is ridiculous.

Definitely not. Ejecting is very risky. If the plane is possibly fixable you would much rather spend the time trying to calmly debug it to get it back to a point where you can land, rather than risk the possibly career ending physical injuries that can come from ejecting.

You also want to maneuver the plane into an area where it’s safer to crash.

The eject button isn’t the safe way out of every situation.

The other pilot situation you brought up isn’t so simple, either. A pilot who panic ejects before attempting to properly evaluate the situation is a risk not only to themselves but to people on the ground.

sschueller•1h ago
Switzerland, if they want something they can fly for air policing is forced to buy the F35 at what every price the US feels fit (even though the contract with Lockheed states a fixed price, naive politicians and consultants found out the hard way). Of course the CHF to USD conversion is fix at a shit rate from many years ago and from what I understand there is no way around that because the SNB did the conversion back then already.

We have no alternative we can get before 2035. They are talking about extending the F/A-18 but since we would be the only ones still using them we would have to pay for that too at who know what price.

The public approved 6 billion and now it looks like it will be way more, excluding skyrocketing maintenance which is not included and a patriot missile system that when it is finally delivered will cost who knows how many billions.

The whole thing is an absolute shit show here and that's ignoring the technical issues this thing has...

orwin•29m ago
With such a terrain, I would guess that agility and the ability to land on highway of in fields without burning all avionics and electronics would have been rated higher than stealth, but it wasn't. Still, the Swiss were offered a fairly low price, and promised low operating costs, and that's the main reason they didn't choose the Eurofighter (which isn't a multi-purpose jet but an interceptor)

Israel's attack on Iran using the F-35 proves it is a very effective, if expensive, weapon.
efitz•1h ago
F-35 is a boondoggle.

$200M for one fighter plane is insane.

If the USA ever had to go to war with this weapon, a huge number of them would be offline at any given time, and every single airframe loss would cause a huge dent in overall combat power.

I don’t understand why our military and political leaders keep trying to buy ridiculously overpriced Swiss Army knife weapons (lots of flexibility but great at nothing) instead of mass producing combat knives (only good for one thing but great at it and lots of them).

I can't imagine the stress of being on this call as an engineer. It's like a production outage but the consequences are life and death. Of course, the pilot probably felt more stressed.

I don't think there was ever a risk of the plane crashing with the pilot still in the cockpit, despite the fact that the headline sort of leads people to that conclusion.

The pilot could eject at any time. Still dangerous, but more of a debugging session to avoid other similar costly in the future than a Hollywood-like "if we don't solve this now the pilot dies"

ChicagoBoy11•5m ago
Very different scenario, but flying my puddle jumper one of the first times after getting my license, once I took off from an airport in Connecticut and was about to cross a large body of water, my exhaust temperatures spiked really, really high, essentially indicating the engine was seconds from melting. But it didn't.

So of course I felt it was a sensor issue (especially since it sounded/felt great), but luckily with the equipment on board I managed a call to the flight school, who put me in touch with the mechanic. I circled above an airport as he pulled up the maintenance logs, we discussed what I was seeing, he noted that there had been a report of a sensor issue that had been squawked, so we concluded I should feel safe to fly straight home.

At the time it felt insanely cool to be able to be doing that WHILE flying the plane. While an unfortunate outcome for this particular pilot, as an elite pilot, part of me thinks when this cropped up part of him was like: "ahh right, this is why I'm top dog"
