As my parents,a friend and myself whom were returning from Conn.,had stop at an main at a traffic light in broad daylight in the evening in downtown New Rochelle,the air had seemed still and all of a sudden we all had looked up an witnessed a smurkey greyish gigantic aircraft,surprisingly we all were dazed or lost at least 3 seconds seemed hypnotized and 3 seconds later we came to see the aircraft which apparantly it became invisible! It had to!
