There’s no proof that it happened though that’s the problem
I think everyone accepts that it happened, it’s where it happened that’s the issue. Twenty-odd countries looking, with ships, aircraft and satellite, and now a nuclear hunter-killer submarine packing the most sophisticated sonar and passive listening gear, but with no clear idea that where they’re looking is even close to where it disappeared!
Bear in mind that the ocean floor around there drops to anywhere from 2000 to over 8000 metres.
That’s over 24,000 feet! As a shipping expert on TV tonight said, it’s like trying to find a suitcase someone dropped in the alps, or probably the Himalayas.
You’d have a better chance of finding a needle in a haystack just by sitting down on it and bouncing around on your bum!
