I was a Us Air flight from PVD to LAX via Charlotte and then on to Vegas. My wife an I were north of NYC when the pilot said if we looked out the left side thet we could see a fire at the WTC. After that we heard nothing until we landed in Charlotte where we stranded for 4 days ( without our luggage). We finally mad it to LAX and drove straight to Vegas that was eerily quiet. We remember that they were offering free shows just to fill the seats.
