Is the thread drift symptomatic of how slow Hill's progress is? Asking for a friend

Ha. You may want to ask your friend what is he comparing the HX's progress to? Hill's been at the HX for only 5 years and started from scratch with a limited budget. Airbus on the other hand, took 10 years to bring the H160 to market and they had a previous model to work from, plus a technology development prototype, and a $billion dollar budget. Context can be your friend.
