A tipster just sent us this photo taken from Gate 14 of JFK's JetBlue terminal showing a fire on the airfield. Sarah Jenny writes, "A woman just flipped out at her husband and threatened to not get on the plane. Some people freaked out, some people not noticing." Others have taken to Twitter to report the fire, with one saying that it appears to be under control. We're currently awaiting comment from the Port Authority, and will update when more information becomes available.

Update 2:44 p.m.: A Port Authority spokesman tells us the fire is a controlled blaze started as part of a training exercise for the FDNY.
