Factual error: An unexploded British 'Tallboy' bomb from World War II is found in the jungles of Burma. First, no Tallboy bomb was ever dropped in Burma. Further, the purpose of the Tallboy is to quake the earth to shake concrete buildings down, so dropping one in Burma's jungle would be pointless. Lastly, if a Tallboy had indeed been dropped, it falls at great speed and is hardened to penetrate concrete structures, embed itself below them, then detonate. It would have been underground, not tangled in branches above ground as if made of balsa wood, for Rambo to easily find.
