Onetrack,
Weren't the Kiwi rig worker "eyewitness" (who may well have seen something, just not the missing plane) and those 8 "earwitnesses" on the coast of Malaysia situated hundreds of miles apart? (Perhaps 750km or more, judging by one map posted earlier). Seems a mighty long way for either (let alone both) to have seen and heard a 777 "vaporize." It wasn't Krakatoa.
