I took this photo at Suvarnabhumi yesterday (Wednesday) lunchtime as we taxied out.
At least 5 (possibly 6) OT 747's just parked up. I couldn't clearly see the one at the far end by the Thai hangar and it didn't have the OT tail markings but you can just make out the red 'T' of the word Thai on the forward right side.
At any rate, with OTG already grounded, Udom doesn't seem to be doing much flying at the moment.
