I been working nights out doors in Florida. I have seen more shooting stars in the last two weeks than my whole life combined. I even saw a huge one like you showed in the picture on my way to work one night. I actually thought it was a flaming plane going down till it just burned out and disappeared. Crazy huge tail like that.
Could a larger one trigger a warning system like the false alarms in Hawaii and Japan?
If they hit the guy causing him to sit in the button, I'd guess so.
They say it was a mouseclick on a drop down menu and not a button on a console. Apparently "missile alarm" and "missile alarm test" are next to each other in the drop down menu. Somebody didn't do a good job with the software.
I didnt see the flash indoors but I hear the rumble, I thought it was the snow sliding off the metal roof. I looked outside and didnt see the huge pile of snow that usually comes after the rumble. Turns out it was the sound of the meteor. The house vibrated slightly during the sound. I am about 15 miles South of Flint
I was walking the dog in the dark last night and saw just a glimpse about 8 pm (didn't have a watch or phone). I'm in west Michigan so it sounded more like a loud sparkler on fire, but cool none the less.
