In both of these scenarios, I figured that once the wreckage is located, a ground team is dispatched to the site and arrives at the scene a short time later, directed by the crew in the search airplane flying overhead or by GPS coordinates relayed by that crew. Kozak quickly dispelled that idea. While it is possible to have wreckage located in an easily accessible spot, he said that airplanes are much more likely to crash in remote, rugged terrain. Since weather is often a factor in a crash, the weather may also be terrible for the ground search. There may not be any roads or trails in the area. This means that the search team will have to follow a compass course through the woods, up and down ravines, in bad weather, sometimes in the dark, to try to find the crash site. Because it can take days to locate the wreckage, the ground search team has to be prepared to survive in the woods during that time.
