I thought the attached page 124 had some relevant artwork for Rockwell and Boeing concepts. The "Flying Sled" looks pretty draggy tough. From "Secrete Projects  MILITARY SPACE TECHNOLOGY", Bill rose, 2008, ISBN 978 1 85780 296 2  The book does not mention the source though.

Here's a couple from "A look back at Recoverable Rocket Boosters" https://media.defense.gov/2021/Apr/06/2002615086/-1/-1/1/RECOVERABLE%20BOOSTERS.PDF
