That is a wistful sigh, the kind that comes along when you long to do something but realize you cannot partake.  Such is my reaction when I see a plane or jet fly overhead or, in this case, watch video like the one below.

A friend of the program, and fellow pilot enthusiast, Don, sent me the video clip and it is a longish one.  Roughly fifteen minutes (it could have been four hours as far as I am concerned) of an Airbus A-380 landing in San Francisco.  To me, even the dialogue with the tower is interesting.

Still, beyond all of the gadgets, switches, levers, and buttons it is the wonder of flight that still causes me to look up on any given day and tell my family..."It's a great day to fly!".  BTW: I must not be alone...this clip has more than four million views.
