Is the Red Cross Search So Botched?

There is no indication that any of the pilots or crew members had a motive to croush the plane. Why are two independent searchers able to find the wreck after 30 years find nothing? I think reason is because i think there is a lot ofilegal activity going on witke the cocaine, and then like all the snake skin and stuff. It almost seems like they were just trying to cover it up quickly. Then where does that lead to next? And before you know it, you could be erin a huge drug operation.
