the objects moved at great speed but silently and quite low.they were clearly visiblewe saw two triangle shaped crafts which moved silently & at great speed over our roof.they were clearly triangular in shape with greenishwhite lights at the three corners & a bright red circular light at the center.their movement can be described as if they were propelled forward in spurts similar to the underwater movement of jellyfish.though this is the first time we saw the triangular crafts from close quarters ,we have sighted different objects at a greater distance,sometimes like avery fast moving reddish white stars, once a bright silvery band,once a circular shape with bright light below in an inverted bowllike end.
