Here's a db dump of all flights in and out of MUGM (Guantanamo Bay) for the last few months.
Guys don't get too excited about blocked callsigns. Military and others get blocked as needed. Some private flights as well. See how many military flight you can find (types that are B52, C17, F15, etc). Look in ,military operating areas and those are mil flights. Most flights operating at KWRI and KDOV are military.
It's a NetJet. That's where a number of people buy a fractional ownership in a plane and the group shares it. It's likely that 8 or 10 people/companies own it and are shuttling people all over the place. Take a look at Aspen (ASE) and Eagle (EGE) between now and January 2. You'll see a ton of NetJet flights. They're fairly normal and operate like a taxi or Uber that a dozen people share.
OK guys - Things are a little slow in CBTS General so I'll hang in here for a bit today. I've been an air traffic controller for many years, tower, approach controls, and Centers as well as the FAA ATC commend center. Been a controller, supervisor, manager, and ran ATC facilities as well as regions of ATC across the US. I"ll answer questions and try to guide you a little if you're spiraling down a rabbit hole that looks interesting but may be a false lead.
I'll be in and out today but will try to explain and help as I can.
First off - the system that all of these sites you're using to track are using the same basic system that I helped develop in the late 80s. It's an FAA system and blocks certain flights at the point where all of this data is mixed together before it goes out to commercial interests (like FlightAware, RadarBox, etc). The original data itself generally comes from FAA ATC facilities with SOME input from other entities.
You won't see many military flights in there because they are blocked for many reasons.
Radar only goes so far out to sea based on distance limitations of the radar being used. You WILL see aircraft that start to "coast" or freeze over water a few hundred miles out - or closer in if there's no long range radar available at that point. ADS-B may help but that data is not on all flights.
There are many military designed areas throughout the system. Inside those areas you will ONLY see military aircraft if it's active - if the flights are displayed at all. Those areas usually have some vertical limit is so some flights may go above or below them.
I'll watch this thread through the day and answer what I can.
Where the "Y" is in NJ is McGuire AFB. Many flights stationed there do training in that area. At the lower part of the flight is Dover AFB. The training squadrons at both bases go back and forth a lot to share practice areas. Most likely a C141 or tanker doing practice maneuvers.
Should anyone see a flight ident or airport/navaid that they're not familiar with, here's the LARGE manual put out by FAA that details every contraction and call-sign authorized. I'm sure there's a searchable one online someplace but this is the core data from which everything is derived.
Call-sign info is about a third of the way in. Further down should be a section where 3-letter call signs are in alphabetical order as opposed to company name ordered.
Here's something to keep in mind from now through Wednesday noon. It's that time of year when all those with jets or access to jets head to ski resorts in the US and Europe. In the US the main concentration is at Aspen and Vail this weekend. The airport idents for them are ASE for Aspen and EGE for Vail. Both are in Denver ARTCC and handled by the same sector there (same radar scope team). Both airports have a control tower and both are served by air carriers as well, so you'll see United airplanes and others. fractional-ownership jets like NetJets as well as private jets will all be flooding in and out of there through noon Wednesday.
Traffic and airport parking for jets is SO heavy this weekend that every arrival and departure requires an FAA approved reservation for a slot to arrive or depart. All slots were completely full within 5 minutes of opening up weeks ago. That happens every year.
The reason those 2 airports might be of interest now is the ongoing purge of swamp creatures. ASE tends to attract a majority of rich Dems and EGE Repubs. Though both are swamp creatures that either have places there or willing to pay huge amounts for hotel rooms.
The things to look for are large gaps in either departures or arrivals at either airport, an unexpected diversions (look at the weather and if there's visibility above 1 mile or a ceiling above 800 feet then there should be no missed slots or diversions). Also look for an aircraft departing either airport that gets diverted long before reaching its destination. On arrivals look for one filed to land at either place but that in mid-flight lands someplace else. I'd think those would be rare since it's easier to just arrest someone after they land in the mountains.
The operation there for the next few days will be non-stop from dawn to dusk - very few if any ops after dark there. If the weather does drop unexpectedly you'll see flights holding all over that area until it clears up or they decide to divert to GJT or an airport in the Denver area (DEN, BJC, APA).
Just letting you now because the ops there for the next few days will draw your attention.
Costa Rica crash - might be legit, but WAY too convenient timing. How damned easy would it be to put a few unsuspecting people on the flight while the Americans head for some other South American locale or someplace else to live under new names. Will have to wait a day or more to see if the parents were involved in anything shady.
Meanwhile, let's see if we get a tail number or company call sign to archive the route.

Most med-evacs use L for Lifeguard. There are others but a simple L is the generic designator. It's used instead of the N in the tail number. So if you're flying a lear jet with tail number N12345 and you get used as a med-eval then you file a flight plan under L12345.
That Challenger is NOT departing from a hole in the mountain - it departed from EGE (Eagle County Airport). There's no radar there so it can't be acquired by the closest radar until about where you see it's track start.
