What makes aircraft pool fires particularly dangerous?

Aircraft pool fires are particularly dangerous because they allow for the penetration of heat into composite layers. This is an important factor because modern aircraft often utilize composite materials, which can be more susceptible to heat and damage than traditional metals. When a fire interacts with these composite structures, the heat can compromise their integrity, potentially leading to catastrophic failure of the material.

Additionally, this penetration of heat can continue to escalate even if the visible flame appears to be under control. The hidden damage in the composite layers can go unnoticed, making it especially challenging for responders to assess the situation. Thus, the risk of further fire development or structural failure can persist long after the initial flames seem to be extinguished, posing significant hazards to both the responders and the overall safety of the incident area.
