Why paper aircraft disappear from popular history

Popular histories naturally give more space to successful aircraft that reached service and attract readers. The Ed Heinemann design story shows that even a substantial professional history cannot list every drawing, proposal, and question a prolific designer explored. Company histories are also edited and collated accounts, so abandoned paper projects can survive only as scattered mentions or detailed drawings outside the familiar narrative. Discussion boards may point researchers toward those traces, but the claims still require documentary checking. The historian's task is to assemble the surviving pieces while making clear where evidence ends and reconstruction begins.
