Quite a bit OT, but I felt a sense of pride that our Navy was involved along with NTSB as mentioned by the Aus PM. And that we work well with our allies.
OT 2: it takes smart and brave men to fly that far from land and do a multiple hour search as part of their daily job. I can only imagine the advance planning, watching the fuel levels, calculating head winds, not getting lost, maybe planning for plan b or a plan c in case of troubles. Nowhere to land and point of no return are very alien to most. I guess I'm stating the obvious, but when you see the maps of where they were headed, it's just such a different perspective from my daily drive, with 30 gas stations between home and work and plenty of terra firma beneath me. Brave and smart dudes - we still do that (at least

)
