A fuel hose was the "material" in the 25M Dave mentions.

Jim and I were referring to two different fires.

The fire at Camden I mentioned was due to use of a composite
shroud in a high-temperature area, since replaced with metal.
Fortunately damage in that case was not too bad.

Jim was discussing a fire on the runway at Keepit.

Thanks Jim for the email clarifying...
