This is an example of a "sneak in" UFO sighting where none of the activity was noticed until viewing this video five years later! We were in the first fifteen or twenty minutes of driving into Joshua Tree National Park before we approached a medium sized rock formation and got the urge to pull over. I started filming the landscape and panned to the right, and stopped. Right before I start to pan back to the left, if you look at the ground in front of the left leaning Joshua Tree in the foreground, you'll see a puff of dust come from the ground before a triangular object shoots upwards and to the right. The shape then changes from a triangle to a blip or thick line. A mini triangle shaped object seems to project suddenly off the the right and upwards, rotating clockwise, with the corners of the object lighting up. By the time it gets to the trees it changes form and looks more like a blip or small cylinder. I searched extensively for birds that can take off "that fast" from a standstill and was unable to find anything at all. Even peregrine falcons, birds that can fly up to 240 miles per hour, only get that fast from a dive starting well above the ground. When watching it or any bird take off, you can see wings pushing against air and gravity to begin the flight...and its "slow"...extremely slow, in comparison to the speed at which this object is taking off. No animal, insect or bird or otherwise, takes off from the ground this fast.
