Pretty far fetched. How the hell did they manage to light a fire every night. Did they carry waterproof matches??? Why didn't they know a direction to take, by sun rising in east etc, particularly if they were trying to get to the coast? If it was so hot during the day, why were they rugged up? Producers/directors should have done a couple of hours walking in this terrain, to give themselves some ideas of the terrain. These guys should have had burnt lips at least, from such sun exposure!
