Other mistake: When Roy and Johnny are at base camp during the fire, they're dispatched to the incident at Jawbone Canyon. While en route, Battalion 5 orders Engine 51 to approach from the north, and we hear Captain Stanley respond, "Engine 51, 10-4," but it's odd that the subtitles read that Johnny is the one who responds. Later, after Tanker 44 tanks 51, Chet says, "Cap, we've got a charged line," but the weird subtitles read, "Captain's going to throw us a line." Subtitles from Universal Studios 2010 DVD.
Other mistake: At the start, when Roy is reviewing the list making sure he got everything, there are two containers of milk on the counter which have their brand names covered. As an aside, watch Chet as he empties the grocery bag and puts the aluminum can in the freezer.
Other mistake: Just as Squad 51 reaches the Tank Motorway, in the shot of the squad as it drives towards the camera before it zooms out, look at the squad's license plate before it stops. Even through the haze, we can see that the plate number is not Squad 51's normal E999007.
Other mistake: When Battalion 5 orders Copter 10 and Copter 14 to make an air drop on Jawbone Canyon, it cuts to a shot of Copter 14 taking off. This is the same shot used in S3, E6, "Snakebite", when 85's guys tank Copter 14 in order to make a water drop where the teenagers' car is on fire down below.
Other mistake: The Battalion chief assigns tanker 76 to assist engines 51 and 60 with the rescue at the canyon. However, it is tanker 44 that arrives.
Answer: It is standard practice to wet down driveways so that they stand out in a long shot.
