The Indian Air Force - Suryakiran Aerobatic Team (Music by Les Lewis)

The Suryakirans are a nine aircraft aerobatic team of the Indian Air Force operating the HAL HJT16 Kiran Jet Trainers. The team is based at Air Force Station Bidar and regularly undertakes aerobatics display at various events across India and other countries in Asia. This particular video was taken at the Combined Graduation Day parade at the Air Force Academy Dundigal in June 2005. The soundtrack is the excellent "Mission Udaan Theme Song" by noted musician/singer Les Lewis of India. The Mission Udaan song can be downloaded from the National Geographic India Website's Mission Udaan download page at http://www.nationalgeographic.co.in/explore/missionudaan/home.asp .

Indian Air Force's MiG 21 Bison's get 1000 flying hours extension | India Defence

"These results
come after NAL's successful completion of Full-Scale Fatigue Testing (FSFT) on
the MiG 21 Bison Airframe C-2090. With this the IAF's Total
Technical Life Enhancement (TTLE) project has come to an end.

The Air
Force's Bison fleet is of 150 aircraft which originally had 2400 hours of flying
as per the Russian certification, however the Air Force went for the Life
Enhancement Test at NAL."

So thats one airframe that has been wringed out in fatigue tests.
