I don't know if its related but my husband works for Qantas and over the weekend all pilots and flight crew were given an eye patch. no explanation except the federal government issues them lol a single eye patch each. My husband joked that maybe they're air pirates now but no one really gets the point.
My guess is that they are NOT, I repeat NOT trying to make pirates out of the pilots, but they are doing one of two things. Eye strengthening exercises or they are preparing them to weather a nuke blast and light flash so they can still get the bird on the ground with a single unaffected eye after removing a patch.
Juiciest tidbit I have seen in a while.
For the commenter below - if issued and in the flight bag in the cockpit and war SUDDENLY breaks out (nuke war tends to be rather sudden.....) while on an 18 hour flight, then a fleetwide message is sent out and patches that are at the ready are installed while the laser light show blasts away..... Sorry, I forgot I had to spell it all out..... I guess I am used to logic and flight ops a little more than most that may not be in the industry. I would love to know if these eye patches have anything special to block out special frequencies/wavelengths of light. Say, super bright nuke lights or even laser lights if we ever fire up our anti-missile laser systems.
