LDEF experiment A0187-2 consisted of 237 capture cells,
120 on the leading edge, the rest on the trailing edge. In
each cell a 2 micrometer plastic foil, metallized on both
sides, covered polished Ge targets. Although all plastic
covers except for 12 cells on the trailing edge failed
during flight, the Ge plates contain many extended impact
features that were apparently produced by projectile
material that had penetrated the plastic foils while they
where still intact.
