Crichton would finally see his real father again, about a cycle later, though this time he encountered Jack when he was younger in 1985. Crichton soon discovered that his presence in the past had altered history and that Jack was now to command the tragic final flight of the space shuttle "Challenger". Crichton and his friends did what they could to fix the timeline, while John avoided any unnecessary contact with his parents. It seems, however, that Jack later caught a glimpse of his grown son shortly after he had rescued the younger 1985-John from a burning house.
