I do not know what luck you have had with using the search function on this thread, but for me, it has been inoperative.
Fortunately there is an excellent alternative: Google is keeping this thread well indexed. You can structure Google searches as follows:
Supposing you want to search for references to NYT.
Then structure your search as:
<nyt site:
http://www.pprune.org/rumours-news/535538-malaysian-airlines-mh370-contact-lost>
Just remove the <> part of the above for your search. (Had to do that to keep it from being truncated.)
For a different search term, you can use the above string and substitute your search term for NYT in the above example.
Maybe we can cut down on some of the repetitive question asking.
