Howewer, Su-25T with low fuel load and no payload is still a good airplane, I never forget the moment, when I was a teenager and was flying from commercial airport, that was adjusted to the miliary base (Novo-Alexeevka), and suddenly all the people were starring in one direction, less than a mile away it was SU-25 performing set of high class aerobatics, within box of 2x2 miles, rolls, spins, loops...everything was well performed... Later, I found out that a pilot died in a test flight earlier on the same day, and this demonstration was an act of respect from his comrades.
