I was taking video of water falls in yosemite national park. i first notice the object in my video when i viewed it that evening. i thought i had accidentally caught a ufo on my video. it is high in the right side of the video and when i play the video it streaks across the top right corner of the video instantaneously from left to right! i was ecstatic when i saw it! it streaks so quickly out of view i figured it had to be a ufo! but my suspicion is that it is a bird at just the right angle and speed to look suspicious?? please view it and tell me your findings? thank you for your time!
