In the lateness of late nights post I neglected to suggest a recent publication which might be much more interesting than my website,
It is a book released last year called 'Guarding Neutral Ireland'. It has (IMHO) a very good chapter on the North Strand bombing. (I say that as someone who has not researched the military archives on the subject.)
http://www.fourcourtspress.ie/product.php?intProductID=785I would say however that a night time interception by the IAC in 1941 would rather more than unlikely with the equipment to hand, Gladiators. Going by my own dodgy website, the first Hurricane did not enter service until late 1942 and there was only one of them. It was July 1943 before we got four more Hurricanes.
If Tony see's this thread he can set you on the correct course.
