I was doing a vfr flight from tobruk to sidi barini and realy enjoying the scenery until i saw this blueish circle.
From a distance i thought it was a lake at first wich is kinda weird in the middle of a desert but when i got closer i noticed there was an airfield (HLBK) in the middle of it.
I checked bing-maps but everything looked normal on it.
Did anybody ever seen anything like this before ?
