Keep in mind for Events the Beau would be heaven sent. They were all over the MTO. They were all over the PTO and CBI. They certainly were there in the ETO. You aren't going to sub the Mossie for that ride as the Mossie is a better performer. But it wasn't there until the end if at all in some cases.
Of the birds we DON'T have, the Beau is by far the one that was involved in combat the longest in the war and in the most places.
