P‑38 Pathfinder
The Pathfinder was yet another unique variation of the P‑38. It was a P‑38J (or L) modified with special ground-mapping radar and served as the lead plane for P‑38 formations who were bombing through cloud-covered targets.
It could often pick out targets and checkpoints which would otherwise be obscured by weather. The operator was housed in the forward part of the gondola with a large side window, but did not have any forward visibility, which a Droop Snoot bombardier would have. Very few P‑38s were modified as Pathfinders.
This model was found on the BritModeller website and shows a great close-up of this configuration. (They have since removed the pix.)
