Factual error: When the camera is panning through the different rooms of USAMRIID it exits out of BSL-3 and as it does a female technician takes her breathing mask off before she opens the door. This is supposed to be the highly infectious room that tests things like Anthrax or H.I.V. yet this woman not only takes her mask off she's not even quarantined or decontaminated.
Factual error: Every centrifuge ever made comes with a locking system that prevents the lid being opened while the centrifuge is in motion, so even if someone was as stupid as the lab assistant who put his hand in a spinning centrifuge, they would not be able to.
Other mistake: The plot of this film can't seem to make up its mind whether or not the Cedar Creek virus is airborne or not. Several scenes show characters walking around in infected areas with and without protection in the same area. At one point Casey's suit breaks implying that he immediately contracts the virus within mere seconds without even having breathed it in yet we see other people walking around with either their face or eyes unprotected.
Continuity mistake: Two Humvees rush toward hospital; an old lady in a pink top is hit by the first Humvee which fails to break sufficiently. She is OK in the next camera shot.
Character mistake: Salt states that the range of their Hughes OH-6A helicopter is 400 miles. The actual range of this model is 267 miles. (Source: FAS.ORG).
Suggested correction: The FAS site lists 4 different ranges, but according to Boeing's own website, the range was 413 miles.
Suggested correction: The range of the OA-6 is 380 statute miles.
