Claim 18:
19. A heat exchanger for providing thermal energy transfer between a first flow along a first flowpath and a second flow along a second flowpath, the heat exchanger comprising:
at least one plate bank comprising a plurality of plates, each plate comprising
a first face and a second face opposite the first face;
a leading edge along the second flowpath and a trailing edge along the second flowpath;
a proximal edge having at least one inlet port along the first flowpath and at least one outlet port along the first flowpath; and
at least one passageway along the first flowpath; and

a manifold having:
a first face to which the plurality of plates are mounted along their respective proximal edges;
an inlet plenum having at least one inlet port and at least one outlet port; and
an outlet plenum having at least one outlet port and at least one inlet port, the first flowpath passing from the at least one inlet port of the inlet plenum, through the at least one passageway of each of the plurality of plates, and through the at least one outlet port of the outlet plenum,, wherein for each plate:
the proximal edge is along a mounting rail;
the manifold first face has a respective associated slot capturing the mounting rail of the associated plate to prevent extraction of the plate normal to the manifold first face;
the slot has a closed first end and an open second end; and
a respective fastener proximate the second end secures the plate against extraction from the slot.
