Enemies on the Horizon-Episode 5: Escape!

The characters have several options in fleeing the hidden base and returning to civilization. Depending how they left the situation in the canyon, they may still have to deal with one or both Nazi spies (if they managed to escape back through the temple passageway), crewmen escaping from the flaming zeppelin, or surviving commandos intent on revenge.

The Nazi cave accessible from the temple’s secret corridors (or from outside if anyone notices it) holds enough supplies for a trip back to the Nile, even at a leisurely pace. Even though the heroes can’t all fit in the biplane, they might decide for one character to pilot it; it serves as a good means to survey the damage they’ve done to the base, scout out any other enemy units in the area, and provide aerial reconnaissance for characters traveling on the ground.
  If they can find the hidden car the Nazi spies used earlier, the characters might also commandeer that for their desert trek home. It’s a bit more maneuverable than the lorry, and proves easier to “unstick” from patches of soft sand. Two MP-35 submachine guns sit in the back seat. It can accommodate the entire group, though it’s a tight fit with necessary supplies.
  Their lorry could use more petrol and some additional supplies, but otherwise can transport them back to civilization reliably.

If escape seems too easy, throw in some additional complications. Any escaping Nazis might pursue them with whatever means possible, including the biplane. Commandos moving quickly could block their escape from the temple corridors or even set up an ambush among the giant statues and back passages in the temple’s great hall.

After her rescue the heroes retrieve the key to the tomb gate’s lock and can return to Sakkara and resume their excavations.
  Miss Doyle admits she occasionally works for the British gathering information about potential threats, watching suspect foreigners in Egypt, and photographing points of interest to His Majesty’s government. Her father served in the army for many years which fostered her strong sense of patriotism.
  Doyle discourages them from discussing these events with anyone. Despite their astounding escapades, the heroes have a difficult time getting anyone to believe them, especially with British, German, and Italian authorities officially denying any knowledge of such a secret base on the Egyptian border. The remote location of the action almost guarantees nobody can truly verify their experiences. The Nazi propaganda machine releases a news story that the zeppelin LZ-129 veered off course after its stop in Tripoli a d was presumably destroyed in a desert sandstorm, but that’s the only official acknowledgement the characters receive of events related to their escapades.
