The low rolling hills in the background are nottheoldest mountains on Earth, but they are up there on the chart. Ozark. We are quite well evolved here!
Airlines aren't going to change out from VCR's in a lot of older planes because anything added has to be resubmitted to the FAA and not just that particular DVD palyer, it has to be sumbitted and cleared to be used in that particular type of plane with the other equipment already on board. So unless it's a relatively new one they aren't going to go thru the expense, or wait for a total refit.
