28 LEFT
If your question is aimed at me, I think that they should be. My take on AMFs post is that he was suggesting that Maxlalt's mate was being a prima donna, where as I read that he was concerned about not seeing the PA28.
Thus I was trying to point out that I was involved personally in a situation where a US pilot was concerned that he could not see (and therefore was not in a position to avoid) and this was perfectly reasonable behaviour in keeping his 727 safe and not at all prima donna in nature - the PSA/172 crash shows why vigilance is important.
