Knight I think this was the only useage by US at night in the ETO. Not sure about night P-61's in the Pacific which I know practically 0 about. Incidently I just viewed an ugly clip 1 hour ago of a nasty US fire bomb that maybe used on the Iraqi ground troops. Destruction/swath cut into a 300 yard by 300 yard area. It appears this may have a similaiar characteristic of the older naphlam, but they did not say what the properties were of this beast.
