Ah, but just because the text quotes 67FS, it doesn't necessarily mean that the aircraft are marked as such. At least one Eagle pictured has a blue fin band whereas the others have red fin bands.
Seen today at a very quiet Butterworth was a single F/A-18B... Not Malaysian, but A21-102 Australian AF, with a Tiger marking. It flew a local mission from aprox 10:30 until 11:18. Hope to see more tomorrow.
