There are over 30,000 commercial flights per day in the USA alone. Assuming the article is only discussing fires on US carriers (doesn't specify, but we'll give it to them). That means that even if all 22 fires happened this year the chances of a fire on a flight is 0.0002009%. Or in other words less than 1 in 497,727 thousand flights. The simple answer is know where the fire extinguisher is. Problem solved. Since in actuality only 1/2 the 22 fires were in the past 3 years the odds today are about 1 in 2.98 million. Compare that to the odds of me having to share a row with a fatty or a stinker which are about 1 in 3.
