IIRC, most of the survivors simply waited near the bottom until landfall, then walked away. I think many of the victims had a choice between jumping or burning, but it definitely seems like a burning envelope is survivable if (your part of) the cabin doesn't catch.

Maybe the focus should have been on making the cabin nonflammable. Suspending the cabin with an air gap, and lining it (especially on top) with serious fireproof and heat-resistant lining, might have done the job.
