Came across this because I flew on the aircraft (N718TW) that is operating this flight yesterday on JFK-SEA and put in the tail number just a couple minutes ago to get the Flightaware info from my flight, and realized today that on its flight back to JFK this morning, the aircraft is currently diverting to MSP (Flightaware says it should be on the ground any minute as of the time I write this post).

Any insight in to the cause of the diversion? I could speculate but would prefer not to.
