This answer about solid-jet-assisted takeoff links to the page B-47 Jet-Assisted Take Off (JATO). An image there took me to a collection of historical aviation images, apparently from a LIFE Magazine archive.
Browsing there led me to the image below, of what looks like several aviation engineers sitting on a very large format drawing of a B-47 aircraft and its major components.
A reverse image search leads mostly to sites written in Russian, which I can't read.
Does anyone recognize what's actually happening here? It's not scene one would normally see these days.
