White/Silver Disc coming from the Atlantic stops in midair to change forms not once, not twice, not thrice, but FOUR TIMES!!

On March 16th, 2016, I was taking my car for a test drive after I had the battery jumped due to leaving my hazard lights on at work. All was running smoothly under the hood after a short cruise south on *Flagler Drive (*a waterfront road stretching the length of the intercoastal waterway, on the Atlantic Coast of S.Florida.) As I prepared to make a right turn heading west onto P. Beach Lakes Blvd; something bright,shiny, white & INCREDIBLY FAST caught my eye. Driving parallel with the object I could see clearly against a blue, cloudless sky; that it was a white or silver disc, heading West, presumably from off the Atlantic Ocean.
Realizing what I was seeing, I quickly pulled into a CVS parking lot & parked facing the object. At this EXACT time, the disc stopped completely. Sitting stationary in mid air.
Before I could think, blink or click a pic, the object literally & almost instantaneously, changed from a white disc into dark grey/silver disc. It stayed this way for maybe .06 seconds, before dissolving/dissipating into what I can only describe as a smear of dark grey smog/smoke. The smog/smoke had an odd form, horizontal with a slight upward angle, . Before I could think about it at all, it changed/morphed AGAIN.
This time into a perfectly white, fluffy, “nothing to see here’” CLOUD. This blazingly fast, white then silver DISC, dissipated into a smear of grey smog (for a split second) then changing one final time into the white cloud.  A seemingly normal, white cloud, that wouldn’t solicit a second glance from anyone.
 My excitement & adrenaline was definitely  elevated after this sighting,  due to the fact that my Husband & I FINALLY saw our first UFO (TicTac!) one month before this sighting. Early February 2021, we spotted the white/off-white ‘TicTac’ coming from the East (Atlantic Ocean) heading west, inland. The size, speed & maneuvers were unmistakable to me & convinced my husband, who is an engineer with 15  years of experience of all things-in-motion, that we indeed have some pretty intriguing visitors here is SoFla!
