To the outsider, this whole story is confusing. OBOGS is great since it doesn't require a logistics system for refilling like liquid oxygen or gaseous oxygen systems do and it isn't a new idea - most military aircraft have used it for decades.

There are excellent finger sized blood oxygen sensors (Oximeters)available to detect hypoxia. Emergency compressed O2 tanks could be made available if the OBOGS system fails.

It sounds more like a bureaucratic problem than a technical one.

Indeed. And we could always limit, temporarily, their operational ceiling until we've fixed the problem. That way we can still use these great planes and avoid the situations where oxygen becomes an issue. Grounding the entire fleet and losing our capabilities when the issue is restricted to higher altitudes, just seems... short sighted.

Unless I've misunderstood the exact problem with the OBOGS.

Compressed oxygen as a backup seems like a no brainer even if they do fix the generation system. Just seems like a good idea anyway.

And where do you suggest putting those O2 cylinders and all the associated gear. Not to mention that it must also seamlessly integrate with the pilot's mask and existing O2 system.

Apparently you've never seen inside the cockpit of any modern fighter, every square inch of space is already accounted for. Internal space in the body of the jet is at a premium as well.

In the nose, in front of the radar installation. There certainly must be some free space there

You are probably more correct than you know.

In my experience with government, somewhere there are a group of engineers and technicians that have at least a temporary solution that has been overruled by a official committee of bureaucrats who see the whole issue as justification for their jobs. The bureaucrats will drag it out as long as possible with as much paperwork as possible to continue to show that they are anything but a waste of salary.

And the bureaucrats have experience building and designing what?

Holy strawman.. what an idiot.
