RAF running coordinated tanker ops across the entire Eastern Med right now
RRR2303 (Voyager KC2/KC3) at 40,000ft over the Aegean was heading west, and RRR9902 simultaneously tracked near Sinai at 28,000ft. That's two RAF tankers in the same window.
The RRR callsign block is dedicated RAF air-to-air refuelling so these aren't transits. Someone was getting fuel out there.
