Open fire and you'll wipe out this enemy patrol before they know what hit them. It almost seems too good to be true. You hesitate and one of the enemy turns round to reveal a familiar face.

Sympathy for the American A-10 pilots who killed Matty Hull has been in short supply in the past few weeks. This has not been helped by America's refusal to send witnesses to the inquest, but one tabloid columnist went so far as to label the incident "murder".

Dr Mancusi says "psychological distance" is now lacking. Instead of the confusion of the past, those involved in the incidents now have to confront what they have done, sometimes immediately.

I thought how humane it was of Matty Hull's wife to offer words of forgiveness to to the US pilots. Civilised society should know that War is horrific and part of that horror must be the potential for accident or human error. I also thought it might be a good idea for Matty Hull's wife to be given the opportunity to offer her words of forgiveness to the US pilots in person to perhaps give them all some peace. William Randell, Leicester

It's hard to feel sympathy for Matty Hull's killers when they hide behind their government and remain anonymous. If they are sorry, they should have the guts to apologise to his family in person.David, Ely

You can not expect soldiers to go out and fight our wars and then destroy them when mistakes happen in such highly stressful situations. Surely it is down to the higher ranking officers to ensure plans are followed correctly and not the guy that pulls the trigger. After all, they are taught to follow orders without question. This does not mean that there should be no responsibility on each soldier to do their very best, but cruel accidents are surely a part of war where the outcome is life or death. Lourdes, London

I understand that mistakes can and are made in the heat of battle when split second reactions are needed. However, I have difficulty in understanding, given the technology available these days, how a plane can attack/bomb their comrades especially since a split second reaction is not usually necessary therefore allowing more time to assess the situation.Gerry Cunningham, Aberdeen, Scotland

Matty Hull's widow was extremely courageous and generous in saying that she hopes the men responsible for her husband's death can now put it behind them - not forget, but move on - and live out their lives in peace doing something worthwhile for the world.If she can find it in her heart to say that, then I believe those men ought to heed her words, and try to do just that.There's nothing to be gained by hating or reviling them: they had no intention of doing what they did, and are certainly unlikely to make a similarly tragic bad judgement call in the future.Susie, Turriff, Scotland

It is a difficult and awful position to be in. One which many commenters here will have had no experience (myself included). I doubt very much that the pilots involved have been going round telling everyone how wonderful it feels to do what they did. The one person to show absolute courage and dignity in this matter is Matty Hull's wife. If the world were full of more like her maybe we could avoid war altogether. An amazing lady.Pete, Kingswinford
One needs to remember that soldiers are not trained based on democratic principles. They are trained to follow orders from superiors who they are to consider infallible. Those superiors are only human and will, unfortunately, invariably make mistakes themselves. Although modern technology has reduced the occurrences of friendly fire, it will never disappear, and we need to support those unfortunate soldiers who receive the wrong orders instead of criticizing them. How a government responds to such an incident is not necessarily representative of the feelings or views of those soldiers. David, Vienna, Austria
