Heavy loaded German BOMBERS like the Me 321 / 323??? Right.
But yes, that thing contained a very small dose of the original "Göring Gas". This special "fuel" was enough to get even the most heavy planes into the air, but couldn't be used on fighters like the 109 because it's extreme power would have ripped the aircraft apart.
Unfortunately it's use was very complicated and one had to make sure that nothing alive was standing behind the plane that used this fuel because of the extremely toxic exhaust gases that would cause every form of life to perish emidiately.
Another problem was that this type of fuel wasn't always available and depended on Germanys food situation and Görings appetite.
