I don't wish to participate in this discussion as pointing out faults with the dead is some what disturbing for me, I shall try to keep it as diplomatic as possible but I request you to drop this topic. The Nishan-e-Haider (and other gallantry awards for that matter where the recipient is deceased) are not meant for the recipient but rather for the nation and force's morale. The recipient could hardly make any constructive use of his reward and their family, proud no doubt, would choose to exchange a hunk of shiny metal for their beloved son/father/brother any day.
As to what makes me think that Rashid Minhas deserved a Pilot Officer Nishan-e-Haider and Sqn. Ldr. Sarfaraz Ahmed did not, well in Rashid Minhas's case:
1) He was young.
2) He refused to ditch his aircraft and save himself.
3) He showed great selflessness in trying to evict the traitor and make him fail his objectives.
In a nutshell, he performed beyond the call of duty (Which was to waste the plane)
As for Sarfaraz Ahmed, he showed great bravery by all definitions but it is important to remember that:
1) After his guns jammed, there was little hope of trying to return to base without enemy engagement.
As a result of which, what he did was brave and showed great strength of character but did not qualify as "Acting beyond the call of duty". A fundamental requirement for qualifying for the NH.
