When Max and 99 want to drive back into the premises they just exited, as the guard checks their IDs you can see the gate is open behind him, even though it was closed just before and he opens it right after.
Early in the episode, Max is attacked by two KAOS killers as he talks to the Chief on his shoe phone from a hotel room. As they start shooting at him, he leaps over the bed and he clearly has one shoe on and one shoe off. But after returning fire, as he walks on the bed to get away, he has both shoes on.
Around sixteen minutes, Max and 99 drive up in front of the hotel after attempting to use the ejector seat. When 99 steps out of the car and down the steps into the hotel entrance, it is obvious that she is wearing white shoes. However, in the next shot when they open the door to a room, she is wearing black shoes.
At 19:55, the Jet Space Laboratories sign reads "Eastern Divsion" rather than "Eastern Division"
