BTW A few hours ago I saw an article in WaPo about the terrible danger to pilots weighting below 136# when ejecting from F-35. :rolleyes:

This has been discussed to death here, delft, go back and read.

The fact is, the ejection seat has certain issues at certain flight speeds with pilots that weigh under 136lbs. Those are very rare circumstances as I understand it. If you weigh over 136lbs it is supposedly a non issue.

There are certain media outlets, particularly those with a certain bias, who are hyping this. Yet, the F-35 is moving forward, and will continue to do so...and numerous nations are continuing with them as the 5th generation aircraft of choice.

I did read it, thus my very limited mention of it. The chances of neck injuries were IIRC 1 in 150 000 and 1 in 200 000 for the lighter and heavier pilots in case they have to leave their office in a hurry. Both very minor chances.

Yes, but to be precise I lb = 0.4536 kg. Precision is not warranted because my weight has been about 75 kg, plus or minus 2 kg for the last fifty years. And I do not weight myself every year.

Well master Delft, the last time I looked?? no one on the WaPo staff had any first hand knowledge about ejections seats, which is honestly a NON Issue? It amazes me that so many folks can have an absolute SPAZ attack over the F-22, or F-35. The WaPo loves issues like this, because it is illusive, as well as divisive, presenting them with another opportunity to appear smart and well informed, whilst their ignorant readers are allowed to feel superior and caring all at the same time, as they join hands and hearts and once again attempt to crucify the US Military and LochMart.

They enjoy a measure of success in these endeavors because many of their readers are not only ignorant, but pious as well?? This concern has come to your attention because the US Military and LockMart are genuinely concerned and instead of covering it up, are saying hey, we can't allow this is good faith, but it will take time and money to get it "perfect", and they will.

Now as an engineer, you should know that every tool, every system has a design limit of operation, there is also a maximum weight on the seat is there not? which means fat-boys and girls won't be flying the F-35, but nobody worries about big boys and girls do they???

No brother, being a fighter pilot will NEVER be "sand-box safe" will it, it is very dangerous business? If they lower the acceleration of the seat to accommodate the Jr. High folks, that will mean the average size dude will spend more time in the "danger zone", as the seat will be demonstrably slower in getting you out???

I can't wait to read the "glowing article" that they print when LockMart or Martin Baker have the fix well in hand??? can you??

Something about the ejection seat I came across today. In the unlikely event of the lift fan failing catastrophically the aircraft would pitch inverted in 0.6 seconds, and the pilot is protected by auto-ejection signalled by pitch rate and attitude. I guess in the blink of an eye you are either out or dead.

and that is just it, the ejection seat is a "Krap Shoot", I would hope God would have his own hand on mine. As we read the details of this concern, we find the finger-prints and hyper-ventilation of those liberal "haters" of practically every article or tool that defend the "beautiful land, they hate it all??? just in their genetics I suppose. The F-35B driver will have it much better than everyone of the V-22??? but that's just life isn't it?

This issue will fade away quickly because it is simply something about nothing when the facts are put out. The probability and the narrow range of potential candidates being impacted doesn't warrant the attention given. It is symptomatic of how a program may and can get out of control if it has to cater to every interest or politically correct leaning. The politicians also need to be pushed back that you can't expect a program to stay within budget if you have to attend to every outlier. Augustines Law Number XV: The last 10 percent of performance generates one-third of the cost and two-thirds of the problems.
