How Many Farts Does it Take to Set Off a Smoke Alarm

Who knew this was possible?  I mean really, I've sat next to people on planes that had gas and actually felt bad for them.  Probably because it's happened to me, too.

Singapore Boeing 747 was grounded after the smoke was set off by farts. The cargo plane was carrying four crew members and a little more than 2,100 sheep. The sheep ripped so many farts that the plane had to make an emergency landing because they set off the smoke alarm.  How many farts doesn't it take to set off a smoke alarm on a plane?  We now know.  Oh, the crew wasn't harmed.  After a shower, they were fine.

And, you thought your job sucked.
