18-Wheeler: You're thinking like I did when this project started. The Gross weights will actually be pretty low as only a couple of hours of fuel is required-this isn't a long haul operation for the most part. And they have new high speed pumps which have emptied the entire load of water and retardant in only 8 seconds. The control panel will allow you to set the type of drop: all at once or segented, with varying amounts. The water has an anti-dispersal agent added to keep it in droplet form, thus making higher altitude(400-800 ft) drops feasable. And they have allready done a study of suitable runways and see no problems. I think they have really done their homework on this one.
