The first eight indonesian AF T-50's (serialled TT-5001 through TT-5008) - of a total of sixteen delivered - have initially worn this blue and yellow paint scheme. It appears that the TNI-AU planned to revive with those aircraft the "Elang Biru" display team, which was active between 1995 and 2000, flying F-16A's from Squadron 3 in the very same colors. The revival plans never materialised though and by now, all remaining T-50's wear a green / grey camo livery as per picture ID 417716. "TT" stands for "Tempur Taktis" or Tactical Fighter.
