He's talking about the importance of propulsion advances. Is that a signal that this next airplane which originally was called anna may is not coming for a long time. is that what. He's gently telling us. Well so really good question i mean the point is is that we simply are in the dark so we just we should admit that up front to to start with so we are as you say.
