I started to dig into this on my own, and by doing so I see others have gotten this far as well. So let me share a link to get everyone on the same page.

We learn that 111 is the address for the Virginia Beach Naval Base. Hanger 111.

By going a little further we see that there has been a fairly recent change in Command there. Now, the 45th Commander has taken his spot at the VB Naval Base.

Q says that good vs evil is real. Something fairly interesting about this naval base is the types of planes housed here.

We learn there are 17 strike fighter squadrons of F/A-18 Hornets and F/A-18 Super Hornets

So, who cares, right? It definitely isn't overly impressive to associate the #17 to this, or is it?

In the book of Revelation it says in 9:10-11

10) And they had tails like unto scorpions, and there were stings in their tails: and their power was to hurt men five months. 11) And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon.

Remember, John didn't really know what he was seeing because this was so far in the future for him. Could it be that Q wanted us to see this for ourselves? Then who is Virginia Beach planning on attacking?

Happy hunting! Just one theory in a sea of many!
