PART 1:
Look at those numbers... 17s and 18s... And yep, this is one of John's planes. He bought it when he and Michael Berman started Random Ventures, before George magazine. 😉As I like to say, somebody's flying that plane, whether it's Jr. or not, and seems to leave clues all the time.

So far, no one can find a name for the person flying this. Just a business name: SKYDOGS LLC. The registration/tail # is: N529JK. John chose that to honor his father -- 5.29 was President Kennedy's birthday.

Times:
7:10=71, 17 flipped/mirrored
8:17=81, 18 flipped & 17
1 hr. 7 minutes=17
Stafford=89=17
Full reduction=35
Virginia=89=17
Full reduction=53, 35 flipped
Reverse full reduction=55=5:5 (pilot's term, "loud & clear")
Stafford, Virginia=178 (you can pull 17 & 18 out of that)
Stafford VA=112=4
Reverse full reduction=59=14=5
(Put those 2 numbers together=45)

i will have to find the images and the original copy of the post, but back on Twitter KelliAnn and George C. the 3rd, found the owner of SKYDOGGS. Shared a picture of him too. Friend of JFK Jr. An Older gentleman. He was seen at the Trump rallies close to the fake Vincent Fusca who is JFK Jr in disguise.

I think JFK Jr flies the plane especially when he does skywriting messages. Other times its probably his friend just flying with no messages.
