( very very sad day, RIP those men of valor who died, fortunately aircraft appears lightly loaded, appears Garuds among those killed in the crash..very sad. I don't think engine failure can be a cause, even with multiple engine failures, they can easily set it down on a rather rugged patch of ground without any serious damage. Some other technical issue perhaps, should be investigated asap and corrective measures taken, aircraft is still in warranty if technical problem due to manufacturing error, the aircraft will be replaced but extremely well trained lives cannot be. Sad day.
A saboteur at Gwalior would be highly unlikely, I don't see how someone can penetrate multiple layers of security in one of IAF's principle bases, I wouldn't rule it out though. I think time for a serious effort to get to the root of these things.
I think blaming IAF pilots or maintenance at this stage is rather silly and stupid, we had two squadron commanders and wing commanders, clearly the aircraft from both ATC and ground witnesses suffered a catestrophic fire of some sort, to me this looks like a serious failure of the aircraft itself. Sure the fighter wing has had accidents due to pilot error but they have training defeciencies but as far the C-130J is concerned, only the best among tranport pilots are chosen to fly these, the C-17 and other heavies, it requires significant amount of training and practical exeprience/plenty of hours before one is given the keys to such a behemoth, to me the pilots are the last ones to be looked at. This is a serious failure in the aircraft itself.
Let's investigate the aircraft for failures and I am sure it will be proven that it was an aircraft failure. We'll get the bird back as part of manufacturers' warranty with the next batch of 6 being built now.
I know it may be hard for many here to believe but IAF does have professionals at work and they take their work very seriously, if the failure of the bird wasn't as catastrophic as it appears, they would have landed it on a rough patch, they have plenty of training to do that.
