David Achilles, who is an award winning director and editor (not to mention an avgeek) completed a very impressive time lapse video of his recent flight from Denver (DEN) to Burbank (BUR) and back while on Southwest Airlines. Before you get angry at David for having an electronic equipment on during take off and landing — have no worries, he received permission from the Southwest flight crew.
Update: I ran a follow up story on how it is okay to use electronic devices below 10,000 feet with the approval of the airline.
