“You can boil almost everything down to three big levers that the business had or the product had on the aircraft side. You basically had we basically, I basically built an, like, you know, electric range equation that amounted to how much powertrain efficiency, like, you know, how high efficiency of the powertrain, et cetera, can, you know can deliver ultimately like the lift over drag, like the efficiency of the aircraft. And then ultimately how much mass is made up of energy and how much energy you have on board. Like ultimately everything boils down to those three levers and it becomes like relatively simple when you look at the first order of physics of that problem.”
