There's no doubt in my mind that eventually the new helmet will be used Service-Wide. The old helmet is a victim of the Digital Transformation. It makes sense that while it is still in use they would attempt another "fix". But there's is no escaping this and the night of the Supermoon among others. "According to an accident investigation board report released in early October, the F-35 in question crashed mainly because the pilot incorrectly set a “speed hold” that was too high during the landing process. However, the AIB identified a number of other issues with the F-35, all of which contributed to the crash. Those included a misalignment and “green glow” of the helmet-mounted display, which both caused the mishap pilot to think he was too low on landing and made it difficult for the pilot to see the landscape during the mission, which was conducted at night." But it's goose was cooked long ago. Just a matter of eMagin catching up with the increased capabilities that the Joint Program asked for and Sculley has mentioned a couple times of late on Public Forums. The CFO saying "we are putting our display into an F-35 helmet". I guess there is a little wiggle room there "a helmet". He doesn't say replacing the legacy display in every helmet.They have overstated things in the past but I'm trusting this is to big for them to step on their... fill in the blank...
