Not quite. Bubble canopies, one left, one right. They were unpopular; even a non-pilot like me can imagine some of the reasons, and one wonders why they were adopted, but bubble canopies on large aircraft was a fashion (B-47, XB-42, even perhaps Canberra B(I). 8, though that's much less egregious). Fighter envy?
