Impossible to identify the aircraft. The bright white lights are high intensity strobes intended to make the aircraft easier to spot in poor visibility.
It is quite common for aircraft to be listed on the trackers as 'blocked'.
This does not imply that there is anything strange or unusual about the aircraft.
Sometimes the tracking systems don't pick up or refresh correctly so some details might come up wrong or indicate 'blocked'.
Two aircraft flying close together along a route is quite normal and as most jet aircraft cruise at approximately the same speed it can look like one is being escorted when it is not.
The two planes may actually be separated by several thousand feet of altitude.
They may actually fly in 'formation' for hundreds or thousands of miles.
TRACKING DIFFICULT TARGETS
Sometimes a plane can be difficult and very uncooperative to track.
This is particularly so with the spoopy 2-#### planes, JSOC planes, and some other mainly military stuff.
In certain regions around the world such as Africa, Middle East, Caspian Sea, Oceanic areas & other remote areas/places tracking coverage can be non-existent, patchy, or unreliable.
To mitigate the problem slightly what you can do when tracking a problem plane is to watch and monitor other nearby aircraft travelling in the same speed/direction.
By following these other aircraft you can estimate the position of the 'missing' or 'uncooperative' aircraft.
If a flight plan is listed for the aircraft you can use this to plot the course & position & estimate where it might pop up again.
Often an aircraft will drop off one tracker system but will still show on another so try using an alternative tracker or two trackers at once.
2-#### PLANES
These aircraft are a bit of a bug bear with there spoopy behaviour.
It would help a lot if you can try and dig into the backgrounds of these aircraft.

So far we have only managed to scratch one off the list. This guy -
2-MAPP
As far as we can tell he is all above board.
The captured flight profile shows a typical photomapping profile. The figure eight loops along his journey are where he has carried out a wind drift check to calculate wind speed & direction.
The zigzag part of the flight is where he is carrying out the mapping part of the flight gathering images/data to be put into maps or to be used for scientific study etc.
As we are pretty confident this guy is on the up & up there is no reason to track/capture this guy unless you spot him doing something odd that doesn't look like a recce/mapping profile.
