I should clarify - I'm to the west of Bal and can't see the airfield here, but am on a very busy stretch of airspace for the IAC - so familiar with the profiles of aircraft climbing out from Bal.
Saw the landing lights initially coming towards my direction and thought it might be the Casa, but what really got my attention was that it appeared to do a very fast shift south then a few seconds later resumed back west.
In a housing area so didn't want to go out into the middle of the road and gawk upwards only to have the neighbours look out and think they have a peeping tom! Also I was up to watch the F1 race from Korea
It's possible I've misidentified some traffic from EIDW going an oddly circuitous route, but don't think so.
(When I say West and South, I'm giving ballpark directions, probably more WSW-SSE-WSW although don't quote me on that! Maybe I was overtired and overestimated the speed and given a casa driver a great laugh.. anyway..)
