Interesting Greek Spartan flight

Today we’ve tracked an interesting flight made by an Hellenic Air Force Alenia C-27J (4122). The aircraft left Elefsis AB, near Athens, this night, for Rhodes where is landed at 07:50 UCT (08:50 CET, 09:50 local time) after a short stop the aircraft is departed eastbound.

The route of the aircraft changed some minutes after the departure and the aircraft was flying southbound when at 08:31 UTC is disappeared from the tracking site. After 2 hours (10:25 UTC) the Spartan is appeared again, this time south of the Peloponnese in flight northbound. The aircraft is then landed in Araxos AB around 11:00 UCT.

Where was the aicraft between 08:31 and 10:25?

We cannot say this for sure because we have no data.
Surely the flight time between the two locations is not two hours. From the outbound and inbound routes it would seem that the plane had gone to Libya (Benghazi?) where it would have had time to make a short stop but, it must be reiterated, there is no evidence of this.
It may also have flown south of Crete but it is difficult to understand why the aircraft disconnected the transponder if it was an ordinary flight (the area is well covered by the tracking sites).
