Metallic sounds and bright flash of light - Seen from indoors with blinds shutWe (2 people) were inside and heard loud metallic grinding sounds. The sounds died down and we saw a bright flash of yellow light illuminate every window in the house for just a moment. Maybe about 20-30 seconds later we heard a huge crashing sound that sounded like twisting metal. I called someone I know about 8 miles from me and they didn't see anything strange. Nothing on the news about crashed planes or anything. Very strange! The weather during this event was overcast & foggy with light rain. No lightning or anything related with these rains. No power outages or fluctuations occurred. This flashing in the sky also happened to me in September 2011 and it lit up the entire sky for just a quick moment and then disappeared. The time was about the same also, which is strange. When it happened in 2011 the sky was clear though.
