I was on a train to college - specifically from the town of march to peterborough - and when the train was reaching whittlesey i noticed two white dots in the sky (i always look out of the window on the train). at first i thought it was two helicopters but the dots weren't moving, or if they were they were moving at the exact same speed which i knew wouldn't be possible, and i didn't see any blades or anything. eventually i realized the white "dots" were light being reflected off of something metal and dish-shaped. as soon as i started looking i was paralyzed and couldn't move, i wanted to get my phone to take a photo but i physically couldn't move, i just kept thinking "i should take a photo so people believe me" and that i needed to share what i'd seen - it seemed really important to share it. the craft hovered for about 30 seconds then moved straight upwards above the clouds as the train passed a bunch of trees that obscured the sky - when the sky was visible again, the craft had disappeared above the clouds. i was scared but interested, i felt entranced.
