At this writing, we (fellow passengers and I) are well into the 6th hour of our delayed departure from Asheville to Sanford/Orlando FL. The gate agents are doing what they can, most passengers are stoic and in fairly good spirits, but this reminds me why I am somewhat less than excited about ever getting on another airline flight. The reason for the delay is a maintenance issue (unexplained).
(additional added later)
To make a long story short, we pushed back from the gate over 5-1/2 hours late only to sit at the pushed back position on the ramp for 10 minutes or more ( probably more, but I don't like to exaggerate) with no explanation from the cockpit. Then it got strange. One of the pilots came on the intercom to say that when the airplane was pushed back they got an annunciator light in the cockpit telling them something was wrong. Then he went on to say that they were doing some paperwork to set things right and we'd be off shortly. I'm a retired jet captain and I've never heard of paperwork fixing an airplane. Just saying.
