Interesting. Our shuttles were Part 91 flights. Just operated like 121 (except we didn't have to mess with TSA nonsense).
Sorry, I shouldn't have been so specific.....it was to facilitate traffic in class A transiting above.
As an aside, I brought a jet up for static display in 2015 or 2016 to the Hillsboro airshow and saw the little Intel fleet. Seemed like a nice perk, or at least convenient means of business travel. My older brother has been an engineer at that site for maybe 15-20 years now, as was my brother-in-law (sister's husband) until he retired about 5 years ago.
