IIRC, no. It wasn't an oxygen generator problem. The OBOGS properly shut down when diagnostic sensors reported a hot bleed air leak (bleed air from engines is used to run a bunch of things). The problem with it being hot is that it'll melt stuff that isn't a jet engine, so the bleed air valves were shut, and thus the OBOGS shut down.

 

The pilot executed his emergency procedures, dove the aircraft, and reached for the backup oxygen system, but he fumbled with it for too long without minding his flight. By the time he looked back up, he was at M1.1, 50 degree dive and less than 10000' AGL. He did try to pull up, but too late. The dive was started at 50000'.

 

Isnt one of the F22 crashes attributed to oxygen problems? I would think an oxygen system checkup is needed.

A real gift for fans of Intruder.

 

This is part 1, rest of it you will find on his channel.

 

I luv the intruder but the Buccaneer steals my heart.

The only way to make sense out of change is to plunge into it, move with it, and join the dance.

After a bit more than one year, two F-2 fighter jets have returned to Matsushima Airbase. But they will only stay for a certain time. All squadrons from Matsushima are still based on Misawa Airbase.

It will take maybe one more year, for all squadrons and the JASDF Blue Impulse to return to Matsushima.

Is there any reliable site describing the declassified details between it, the SU-35, the Su-27SM and the others?

Designation suggests analoguous to Su-27SM phase 2 proposal update (Irbis or ESA radar/fc and vectoring engines added), where the Su-30M is analoguous to Su-27SM phase 1 but with 12 pylons (N001V).

 

Northern and Eastern commands kept requesting two seaters I know that much, crew fatigue on long patrols with single seats is a factor. Everything got organisationally messed up when they dumped/absorbed the PVO into VVS and army district commands, hell I think some missile regiments even got handed over to navy.

 

I think they changed their minds about their Su-27SM updates supporting a small purchase of Su-35 (ESA/vectoring), and went for the two seaters to the same spec instead, like India did. Kinda makes sense, with the patrol range thing. Even though not a tandem (pilot/WSO layout), they found back in the 60s-70s especially on the long arctic patrols in those big Tupolev interceptors, it helped to have multicrew to talk to each other or they started going a little crazy over the ice out there.

 

Anyways that's best I can gather from places like Milavia. Mikoyan and Sukhoi, etc., the manufacturers themselves are pretty forthcoming, they really don't go in for the whole "industrial secrets are national security" thing americans love so they'll probably give a press release soon listing specific fitments and show photos of the weapons systems.

Can anyone find the picture of real A-10 pilots training in a classroom using T-Flight HOTAS' on DCS A-10C? Thx

This version of the events, although perfectly plausible and a correct representation of the AF investigation, is currently disputed in court. And I would say very rightly so.

 

There would have been no incident whatsoever if the OBOGS didn't shutdown. If you think that an OBOGS system that shuts down during combat manoevring whatsoever is an acceptable thing, you're dead wrong, as well as the US top brass that produced this very questionable and to my mind disgusting assessment.

 

Furthermore, there is no way whatsoever we can ever know whether the statement "but he fumbled with it for too long without minding his flight. By the time he looked back up" is actually true. It is just a very plausible explanation, no hard fact. Claiming this to the detriment of a pilot's honour is very stark an attitude from a seat.

 

I would rather be more careful before expressing thoughts about why a trained and experienced pilot failed to save his own life. I kinda guess he had a higher stake in this than we have.

Think I think you aren't rightfully considering what was written.

I think it's prefferable to shut down the OBOGS and go to EOS instead of the aircraft catching fire. I guess you didn't understand the consequences of a hot air bleed leak. It will easily set the aircraft on fire and destroy it. You may as well say a bleed air leak is unacceptable during combat maneuvering. Or any other failure whatsoever - guess what, in reality, this stuff happens. Period.

The OBOGS didn't fail. It's driven by bleed air and it shut down when the bleed air valve was closed to prevent an onboard fire.

The fault in this case is with the EOS, or at least so they claim or suggest, I don't recall which.

What detriment to his honour? Disorientation and channelization is a very real danger in the air business. He wouldn't be the first pilot to die because of it, and he won't be the last - his circumstances were particularly difficult, compounded by the loss of fov as as well as motion within the cockpit due to his NVGs.

So because of a warm and fuzzy you want to disbelieve the report? Edited by GGTharos
