Your stories of flying with your father warm my heart! You describe Starship in exactly the same way that I feel about it. What an absolutely remarkable aircraft. So glad you're enjoying it. Short answers...
The sun visors are like that in all my aircraft, because I remove all glass elements in the first LOD model. Otherwise, they seem to cause graphical issues like flashing with some export settings. I've been meaning to revisit this for a long time to see if anything has improved over the years.
I have taken note of your career mode request. I have had relatively few requests for career mode compatibility for all my aircraft since MSFS 2024 released, which I was quite thankful for, if I'm being honest. The requirements for career mode approval from Asobo are extremely onerous and arbitrary for aircraft developers, so it would represent an investment of many weeks for my entire fleet. Nonetheless, if I get enough requests, then it shall be done!
Thanks again for your stories, and please let me know if there is anything I can ever do to improve your flying experience for you and your father!
