Three fast moving violently churning out of place red and black clouds

The date and time of this occurance is my best guess from memory. I knew what I had taken a close up photo of, but everyone I showed it to back then either laughed, or llooked at me like I was crazy. I put the photos away and for years they just sat in a box. Then I saw the movie Independence Day, and it reminded me of my photos. I had three, but I have lost one which I believe would have been proof positive, since it was traveling away from me and not towards me as they are in the two photos I have and want to send to you.
 The location of the photo, was Fox Plaza on Hylan Blvd, near New Dorp Lane in Staten Island. I noticed off in the distance, three very strange looking clouds traveling in a V formation from northeast to southwest. If I were to guess their speed, I would have to say eighty (80) to one hundred (100) miles an hour. As they passed me they were almost directly over Hylan Blvd where the traffice was moving at 45 MPH. They were traveling at least twice as fast as the cars they passed over. As you can see in the photos, the direction from which they came had white and golden clouds, so these three very dark clouds were very out of place. What caught my eye was the violent churning of the clouds. The tops were black, whwile the bottom of each was flaming red. The bottom red part of the cloud was churning up into the middle of the cloud. To best describe it imagine a fuel explosion where a rising cloud of burning vapor is churning up and into itself. From the time I first saw it, and till it disappeared, the violent churning motion was clearly visible.  However, these three clouds never rose but did maintain a constant and steady speed, maintaining their formation.  These clouds did leave a trail which can be seen in the photos as puffy trails of smoke. They made no sound at all as they passed almost directly overhead.
As I watched them I had this very erie feeling, and when they passed overhead at about a hundred and fifty feet, the hair on my arms stood up. I am sure that you can determine their speed since there are buildings in the photos. Please look at the puffs left behind, and the white clouds, and then at the UFOs, and how much they changed their shape in a matter of seconds. As I said, the inward churning of these clouds was very violent. I have never had any doubt since I took the photos of what they are. I only wish it were a motion picture camera I had that day so everything would have been recorded in real time instead of snapshots.
Witness indicates that the date of the incident is approximate.  PD
