Hi Brian,

If not methanol, then perhaps ethanol  (which can be found in abundance in first class) ... ;-)

While I appreciate your concerns, you and I have both been around long enough to recall that for many years folks used to carry cigarette lighters on board aircraft (both Zippo lighters filled with cotton batting and lighter fluid and the butane type) without significant incident (at least to my limited knowledge). We both know also that those days are gone now forever.  

I suspect that the developers, even in their enthusiasm, are at least somewhat sensitive to the concerns you have. As always there are risk and benefit that must be balanced. Considering both point and counterpoint, as you and others here do so well, is key to coming to good solutions.

Very best regards,
Joe
