It's incredibly difficult to build an airplane, especially a completely new design.
It's absolutely impossible to do that at the same time as making one that will last 30-50 years and have a low failure rate.
What is difficult, incredibly expensive, and very time-consuming, but possible - barely - is starting with the first airplane and eventually getting to the second.
The first is the job of a Skunk Works. The second is the job of more traditional aerospace organizations.
