I know how a turbofans/jets work. My comment had nothing to do with the comparison with turbofans, and only that large amounts of air is being moved. > It's the other way round - a Jet gains efficiency the more air mass it can 'process', because larger mass means you need to throw it out at a lower velocity to get the same impulse from it. How is it the other way around, I explicitly said a Turbojet sacrifices efficiency to increase exit velocity.

Firstly, if you are gonna poke holes in other people's arguments, don't get defensive when someone corrects you, especially when you make such precise and well qualified claims as "Shitton of air". Neither were also not spesific about Turbofan vs Turbojet. Regardles of which one it is, the point of the previous poster stull stands. His point of comparison is how reaction mass compares to the weight of the vehicles. All jets move less air, by mass, than helicopters do, when measured as a fraction of the vehicle's mass.
