The B-36 Started With Just 6 Engines...Later 4 Jet Engines Were Added. These Jets Were The Same Engines Used On The B-47 Medium Bomber. Over The Arctic, The Tail And Wings Were Painted Red So If The Plane Was Down, It Could Be Seen From Above. When I Flew On The B-36, It Was A Ten Engine Aircraft. The Crew Was Always Urging To Red Line.
