The thing is VTOLs are not a new system. They've existed since we got jet engines. They shouldn't take a step back and then a step forward to return us to a spot only slightly forward of where we were at. Especially with the long times it takes to get updates pushed out. If they're going to add in tilt exhausts for jet engines to compensate for the turbines they're adding in, they should add them both at the same time so we only get gains instead of a minor gain for a major loss. Step-wise introductions shouldn't involve removing something that you had only to give it back months later.
