Flight AVE13 was the doomed prison flight that had crashed landed in a lost world somewhere in the Saudi desert. Parts of the plane were scattered all over the lost world the only known part of the plane landed was the back of the plane in a snakes' den in which all but Rattle died from either the crash itself, the venom from snakes from the den, or both.
In Lucky's profile she used parts of the plane to use as bombshells in her bombs.
In Impera Slone's profile it is hinted that at least some of the casualties were prison guards, who either died either in the crash itself, or by the prisoners themselves.
