This replica helmet based on those seen in the '80s network series AirWolf has a "fully-functional Speed Visor," as well as an "LED targeting bar" and some other stuff, like five switches to boost up to Over-Awesome. It's available on eBay right now for $900.
Relatedly, I have a message for Geraint Wyn Davies. If you are not Geraint Wyn Davies, you may leave the post.
Mr. Wyn Davies, I knew Ernie Borgnine. I flew sorties in Korea while blotto on stinkum with Ernine Borgnine. You, sir, are no Ernie Borgnine.
