Flew south for some meetings, was booked to leave on Jet Blue from Dulles, but when we were getting ready to board They announced on the prior flight there was a shudder on the landing and needed to check the breaks 1hour. Later announced Ground Taxi Test 1hr. Then came on and announced that the the plane wasn't accepted. Everyone made a mad dash for the Que. I was fifth in line. Ended up catching a taxi to Reagan from Dulles for a flight 2 hours later. Finally got here though, thankfully the same day.
