Looks like OP is taxing for takeoff with only a 50 minute delay. Flightstats is showing that 4 inbound MSP GoJet flights were diverted this morning (to EAU and FSD) -- 6187, 6265, 6216, 6202. OP, have you considered that the pilots on one of the diverted flights may have been scheduled to work your flight? Just because the aircraft is at the gate doesn't mean there are actually pilots available to fly it.
