Sneaky one Andrew. No more artist`s impressions or we`ll be into Luft46 and other what-ifs. >:(
It wasn't an artists impression Arrow. The image Andrew posted is real.
The XP-67 Flew quite extensively during 1944 until the constant engine problems caused them to stop development, If I remember rightly the engines caught fire during a ground test and destroyed a significant wing portion.
If memory serves there may also be a mention of it in Chuck Yeager's autobiography.
