This is the eighth mishap so far this year. Of the eight, the Mig-27 have been involved in four. This is not good at all, for the Mig-27 has typically had a better service record than the Mig-21.
Besides, what happened to them grounding the entire fleet in February to 'inspect' for damages and malfunctions? Wasn't that supposed to have pre-empted these? Funny, how the Mig-27 suffers its worst year after a military-industrial corporation completes an upgrade program on it.
