God knows what happened exactly, the inquiry probably put the blame on him but as such he is a Wg Cdr and one would not expect such mistakes from a senior pilot unless this was part of high intensity ops and he was just fatigued.Yups its Hashimara crash.
Listen at 1:50 , When enquired who is pilot, response is wing commander Oswald.
Although it might be my eye, but I think the Wg Cdr was trying to avoid his No.1 who is the one that seems to have changed his direction.
