Formula 407 - S1-E12
Other mistake: At the start, the episode's textbox reads, "Fort Frazier Ordnance Testing Facility" with correct spelling, but in the next shot the base's sign reads, "Fort Frazier Ordinance Testing Facility" when it should actually be "Ordnance."
Vampire Bats and Scaredy Cats - S2-E2
Other mistake: When the Mystery Company find a torn paper in a coffin, it is written exo-6 and something else. They find later that exo is the first part of exotic. The way the paper was torn, you should be able to see the lower part of the missing letters.
Angel Blues - S2-E21
Other mistake: Kelly is on her car and she is having a phone call with Bosley and the other Angels. However, neither of her hands is holding a phone. In addition, the person on the car is obviously a double/stuntwoman; her hair is different. (00:33:50)
Other mistake: Due to her bionics, Jamie has the ability to leap up 1 or 2 stories of a building or balcony. However, in the episode with the spacesuit, near the end, the astronaut has launched about 40-50 feet in the air, which is roughly 4-5 stories, but Jamie is somehow able to leap up high enough to grab onto the cable and deactivate his suit. (00:43:00)
Other mistake: Carmine throws the gun on the couch and it goes off. The bullet hits in the opposite direction the gun is pointing.
