The majority of the latest posters on this forum appear to believe that 370 went down in the area which is currently being searched.
But where is the solid evidence to support this belief?
As far as I can see there is none...
Well they did use satellite data to predict where to search and when they looked in that area they heard locator pings. I'd say that was reasonably good evidence certainly worth following up for perhaps two years bearing in mind they can't actually search all year round due to weather.
As stated previously, I believe that it is time for a review of all available data and a total re-think of the entire situation.
What makes you think that investigators haven't been reviewing all the data made available to them on a regular basis? Someone is signing off £million bills and I doubt they would be doing that without regular reviews.
