B-36 not the bra

[727Sky]

If I remember the reason for the "push " system was the large propellers that would of disrupt air flow over too much of the wing  reducing the lift. 
Using the push system with these engines was not a good idear as the air intake for the engine was designed to use air that had been heated by flowing over the engine. Because the engine was the "wrong" way round cold damp air was fed into the engine. This meant at times the air intake would start freezing up changing the air mixture for the engine to rich ( too much fuel to air). So then fuel gas starts leaking past the piston rings into the inside of the engine. As the ice builds up more on the intake the mixture becomes richer and there comes a point when burning fuel gets past the piston rings and starts a fire inside the engine.
Because the engines crankshaft was made of magnesium ( to keep weight down) once that started burning its game over. The air problem was partly solved by  heating the intake air.
I believe the B-36 was something that was built to scare the Russians but was only meant to look good but not something the U.S. wanted to use long term so they never solved most of the big problems this aircraft had.
If I got anything wrong please let me know

Sounds good to me .... I just know that there was more than one time when coming back for a landing one engine was shut down and feathered..
