I was driving south (east) on i-35 just outside of kansas city, missouri on 8/08 at 6 pm. it was a cloudy day so i was checking out the formations when i noticed a darker triangular shape, just, hanging out. so i pulled out my phone and recorded what i could. i don't like to be on a my phone and drive at the same time, so i did not record for to long. the triangle stayed there from what i observed to be at least 3 minutes. that time span being from when i noticed it until i eventually got off the highway and headed north to then be obscured by the tree lines. what do i think it is? well ether some sort of physical vessel that is "cloaked" and is interacting with the atmosphere to still show form. or something that was big triangle shape that had passed through the clouds leaving a "trail" or "foot print".
