Have you noticed that it is often very difficult for search teams to find airplane black boxes after accidents? Here are some ideas on how to solve this issue. One solution is to put an airbag device where when the box hits the water, an airbag full of air will open up and the box will float to the top of the waters. Second idea is that the black box can contain unharmful coloring so that it will be easily seen from the skies. Third idea is to put a bunch of food so that sharks and other sea animals will be attracted to it so when there is a search for it, the search team can try to find areas that have a lot of sharks or other sea animals roaming around it. But I like the air bag idea the most. Or it can be a combination of all three.
