Did it use turboprops and jet engines? Are are they takeoff boosters?
Turboprops? what new-fangled ideer is that?
6 Pratt & Whitney R-4360 Wasp Major air cooled radials - 28 cyliners/engine, 2 sparkplugs/cylinder - plug change: not a minor job
The twin podded jets near the wingtips weren't for take-off boost, spanalot. They were wound up and ran with the rest of the engines.
Jet engines were just becoming the Next New Thing and the B-36s were more of a test bed for their development. Thrust vs, Weight.
Jets were lighter, but the Behemoth already had 6 monster Turbo-Props. So, they stayed with that configuration until the B-47 made its debut.
