Japanese F 35 reported missing?

a reply to: Zaphod58

You can perversely say that if modern turbofans suffer unscheduled maintenance or spectacular failure every X -amount of hours, the two-engined aircraft is twice as likely to experience failure each flight hour..

Also in most designs the two engines are located side-by-side, so if one fails spectacularly, odds are high the other one is affected as well. Anything leaving the engine case is highly -likely to it something flight-critical in modern combat aircraft -- either singles or twins.

The flip side is the second engine does provide a safety margin in the event you shell only one engine. Whether that is worth the cost and weight penalties is a debate that twins are gradually losing.

Canada's loss rate with Hornets has not been statistically better than Falcons, for instance. It's also more expensive and maintenance intensive. It's generally heavier. If we had engines that would enable F-15 size fighters and larger to go single engine, that would be the choice today. We're getting close, but until then large combat aircraft will still be twins.

But not generally because of safety concerns. That's not really a selling point anymore. Back when engine lifespans and time between maintenance intervals were a lot smaller

Which really raises the question of if they were ready for this level of complexity.

They're not involved in the avionics though, right?

It might be they are operating under very limited conditions while introducing the jet to service and every fault or indicator light is an immediate RTB condition. "Emergency landing" might be a little overstated.

Why? Why wouldn't you have at the very least the P-8 keep looking? I can understand not having destroyers out burning the turbines in circles but the P-8 is new and we were all told it's relatively affordable to operate and has the best tools for the job.

Because they have other requirements that need to be met. At this point you need specialized equipment to find the wreckage that ships and P-8s don't have.

It's probably abducted by aliens.

Rumors have it that the P-8 may soon be able to deploy an intelligent small submersible for difficult recoveries. The time for one is now, like in the cases of MH370 and even this, but certainly not an official story.

A salvage ship will be better. They can stay on station and use their ROVs to cover the area. There are also a few new long duration submersibles that can cover a large area while the ship stays in one location.

Yes, I remember that a company just won a huge contract for unmanned submersibles, but I could not find the article for some reason.

There was an ATS thread on it...

Echo Voyager underwent its second round of testing last summer. This would be a good test for it.

Just love that kind of technology. It will become super important.

While on-station ships that deploy these have superior staying ability, the Navy has always had the attitude that initial "time on station" was the most critical aspect , especially if you knew the relative position it went down. Perhaps a combination of these technologies will be used.

The wreckage has been located and efforts being made to recover it.

The Japanese F-35 that crashed off the coast of Japan has been found, and recovery efforts are underway, a U.S. Air Force commander has said. “The aircraft’s been located. It’s now in the recovery aspect,” said Charles Brown, Commander Pacific Air Forces, in a briefing for reporters in New York yesterday.

That's good to hear.

I'm assuming the pilot most likely didn't make it either as there is no mention of him.

Just happy that we have control of our tech and not some nefarious scheme happening abroad.

a reply to: RexKramerPRT

They've backed up off of that statement are instead saying that it hasn't been located. The truth is probably somewhere in the middle at this point.
missing F-35 still missing

That article was from a few days ago. That was when they first reported they had found it, then backed off. The new report is from yesterday.

Part of the aircraft data recorder has been recovered. The altitude and airspeed module is missing though. What appears to be aircraft wreckage is near where the recorder was recovered.
