Ever heard of the shoe bomber? If he had had a lighter instead of wet matches we would have had another airliner brought down.
Yes, I have. The primary source of the threat was the presence of explosives in his shoe, not the presence of matches. Because shoes were also involved in that particular attempt, should we ban them next? How about the freedom to use your hands on a flight? Handcuffing all passengers certainly would have inhibited the shoe bomber's efforts.
Material bans on airlines need to be acutely focused on actual threats. Not on potential accessory or tangential items. That tendency is rapidly leading to ludicrous ends: Ban belts; they could be used to hold dynamite around a terrorist's waist. Ban tape; there is nearly always some electrical tape used in those bombs. Etc.. ad nauseam
TSA: If your intention is to bankrupt the airlines, then just keep on doin' what yer doin'.
