The demolition of an old Xerox building in Dallas today (Sunday, February 1, 2015) went off without a hitch. It is interesting to note the bit part played by a drone sitting over the collapse and no doubt taking thrilling video. You can see its two tiny lights at the opening of the video as it hovers just below and to the right of the contractor’s sign at the top of the building. As the building goes down the drone descends for a better look before whizzing off to the lower right at about 17 seconds.
