Not sure what you're trying to say? Light, dense and very powerful electric powetrains need to keep evolving. As we've seen there are very good use cases today for fully electric passenger planes, even for short flights and very good uses case for hybrid planes as well. It's the paramount aspect of electrification, it draws attention, saves weight and reduces costs exactly like battery tech innovations. The reality is that take off is very power intensive as well as other parts of flight. It's very very important.
