"7000 ft" sounds wrong to me. That's over a mile of hose. Feels like that's unnecessarily long. I'd love to learn more about this. Anyone know when or what fire this was?

If they were all in a single line it probably wouldn't have worked -- series hydrodynamic hose impedance adds just like series resistance in a circuit and the pressure at the end would have been too low to be useful. But if it was 7000 feet arranged in several shorter parallel lines it's possible.
