Quoting Aeroflot777 (Reply 4): That's what I wondered when I saw it. I'd think the trucks will go on the grass, just to get to the scene as fast as they possibly can.
It would depend on the condition of the grass, I would think. If it's on dry firm mostly level ground sure, but if it's wet and soft there's the considerable possibility of the very heavy aparatus getting stuck (even more so if there is a significant slope).
On the other hand one of my uncles is a firefigheter for the City of Fresno (California, home to FAT) and has the reputation of being "last called, first on the scene" because as he puts it "A fire truck can drive over just about anything and win."

ARFF trucks carry a lot of water and AFFF, and tend to have a high center of gravity. From what I've heard, high speeds and uneven surfaces are a recipe for a roll over in one of those things. Besides, you'll find ungraded ground, wet areas, and raised drainage culverts hidden in the grass outside the safety areas. Some taxiways have shoulders that can't support the weight of an ARFF vehicle, and the airfield maintenance guys would probably get ticked if a fire truck blasted off a taxiway and took out a bunch of edge lights in the process.
That sim was pretty cool looking. I wonder if the Snoozle works?

that demo did indeed look like some fun, although extremely unrealistic in respect to the capabilities of the ARFF trucks.
those truck would have most definately rolled on all of those turns due to the high C.O.G as previously stated. A Stryker at MEL jacknifed at 10kms a hour going full lock because of the forward motion of water and AFFF under brakes (commonly known as inertia).
Other worthy point to notice is that the monitors going hammer and tong up the top will only last for around 45 seconds before water and AFFF is exhausted.
Contracts and standard regualtions at different airports vary but plans are devised for routing to just about any given point on an airfield and a 42 tonne truck will avoid leaving the tarmac unless absoloutely no other way is viable.
Last point to notice is the distance the trucks were positioned in relation to the aircraft, far to close the monitors for the most part are capable of covering a 747 nose to tail hence the need to be so close is not apparent, that said this simulator isnt reality for training fire crews merely a bit of fun and fun it does look.
