I wrote a fic once where Nightwing has the Golden Eagle suit delivered to his care after Charley Parker's death in Titans Hunt. (This was during the period when Charley's origin (such as it was) made no sense, since there was no link to any suitable Hawkman)
Dick finds out that Charley had been something of a smart kid in his day, and a college student in his early teens. There he'd met older student Hector Hall, who'd been wanting to build a battlesuit out of Nth metal, but didn't have all the science smarts required to construct a functional suit (never mind one with energy blasters). So Charley helped in return for a small quantity of the Nth metal for himself. Shortly afterwards he had a bit of a mental breakdown, dropped out, became a surf bum, but had kept the suit he'd designed, and a short time later debuted as a Golden Eagle. Charley trusts Dick to find a use for the somewhat trashed costume, and so Dick dcides to use some of the materials from it to create his glider-wing suit.
I thought it tied Silver Scarab, Golden Eagle, Hawkman and Dick's never quite plausible glider costume together quite nicely...
