Frustration, worry and fear

We're on our way home after a wonderful holiday in Miami.  However, it could all turn to disaster on the last leg home.  We have a 45 minute stopover in Raleigh Durham Airport, during which we have to collect our luggage, drop it off at the transit desk, go back through security and get on our connecting flight to London.

Problem:  our flight in Miami boarded 10 minutes late, waited another 15 minutes for a baggage issue to be sorted then taxied around for 20 minutes before takeoff.  And we are sitting in the second last row of the plane.  Will we make our connection?

AARRRGGGHHHHHH!!!!!!

(Oh and they just told us we will land 10 minutes late.)
