Factual error: It is roughly 120-135 dB inside of a C-130, especially one that hasn't been specifically modified. It is so loud that it is painful to be in the cargo hold without hearing protection (besides it being outside of military regulations) and you certainly couldn't have a normal conversation while it was in flight.
Continuity mistake: When Ahmanet enters the Crusader burial chamber, she walks in holding the dagger with her right hand and then picks up the stone. As the camera takes the close up shot, it is very clear that she picks up the stone using her right hand. When the shot changes, she is now seen holding the stone with her left hand.

Trivia: At one point, Jenny grabs a large book and hits a man over the head with it during a scuffle. She actually hits him with a book that is modeled to look similar to the "Book of the Dead" from the 1999 "Mummy" film, and even includes the star-shaped key-hole cover. A cute "blink-and-you'll-miss-it" inside-joke thrown in as a nod to the previous "Mummy" franchise.
Jenny Halsey: Whatever's in there has been safely hidden for two thousand years. This isn't a tomb, it's a prison.
