jcjeant,
The inadequacy of the search on June 1 has already been discussed; your cover-up idea adds nothing.
The Brazilian Air Force and the French Navy overflew the impact point on June 1. The French-registered ship Douce France searched the area of the LKP on June 1. Neither the ship nor the overflights saw any sign of AFF447 having crashed where it crashed.
There has yet to be an explanation for why the search on June 1 failed so miserably. Hopefully, the BEA, or the French government, or the government of Brazil will explain why this is so.
What would you have done after you receive the reports from the search planes and ship on June 1 that nothing was found near the LKP? Would you keep returning to that area day after day because you believe that's where it must be, or would you send your limited number of planes and ships searching in other areas?
As it was, it was a passing merchant ship sailing way north of the LKP that discovered the floating wreckage, and not the governments who were searching.
