Jack ONeill

• Mixed Signals (Stargate/Sentinel) by Lori Wright
  This is a Xover between Stargate and The Sentinel. When Blair Sandburg unknowingly shows a member of the SGC a picture of Egyptian-like ruins found in a dig in Peru, it causes an avalanche of circumstances, which forces Jack O'Neill to head a mission to Peru.
• A Very Special Dig (Stargate/Time Team) by Sally M
  Stargate SG1/Time Team, probably the first and last time anywhere ever.
