Flying a squadron of 4.5th gen fighters in Egyptian Air Force livery over most of Eurasia, ferry flight or not, could seem aggressive and be unnecessarily problematic.Presence of the KJ-500 makes it seem more like an exercise than delivery? Also, isn't it more likely to ferry the J-10s from China to Egypt instead of disassembling and freighting the parts over by Y-20?
Or maybe this is just the support equipment?
What's more interesting is the KJ-500. An insurance policy against US/Israeli sabotage? Like a stealth suicide drone?
