I beg to differ..... how about 2 Merlins
You may well be right - I've think I've only twice had the privilege of hearing more than one in the sky at the same time (Spitfire + Hurricane at Wanaka a while ago now, and more recently 2 x Spitfires at Temora), much less two (or four) in the same airframe.
Somehow I still lean towards the crispness and purity of 12 synchronised exhaust stacks as a solo instrument, however a duet will still be worth an ear to the sky
Thanks for the pic of the duo Mustang BTW. I'll read up on it - be interested to know who's the PIC.
