FEMA 2002: broken water main, no manual firefighting, and FEMA's own low confidence
- what the source states
- "WTC 7 collapsed approximately 7 hours after the collapse of WTC 1. Preliminary indications were that, due to lack of water, no manual firefighting actions were taken by FDNY." On the water supply: "It appeared that water on site was limited due to a 20-inch broken water main in Vesey Street." And on its own conclusion: "The specifics of the fires in WTC 7 and how they caused the building to collapse remain unknown at this time. Although the total diesel fuel on the premises contained massive potential energy, the best hypothesis has only a low probability of occurrence. Further research, investigation, and analyses are needed to resolve this issue."
- what we infer
- Independent of the later federal investigation and earlier than it, this corroborates the unfought-fire condition. Its final passage is also the honest baseline for how open the question was in 2002 — the first official study rated its own best explanation improbable and asked for more work.
- limitations
- Explicitly preliminary, conducted without the site access or resources of the later investigation.
- Its diesel-fuel hypothesis was superseded by the later investigation, which found fuel-oil fires played no role.
