Taxiing challenge
Based on my experience working on light airframes, we would often go to collect and aircraft from the other side of the field and then taxi back to the hangar.
The challenge was not only discerning the taxi ways but also the myriad of student pilots and often the 'too late to have flown in the war' type members of the flying clubs who invariably had Spitfire tie pins along with some semblance of a handlebar mustache but little common sense.
If Boeing can get the Loyal Wingman to autonomously negotiate it's way across an airfield's taxi ways with several flying clubs based there, and do it on a weekend, it will be able to handle any of the dog fighting stuff easily.
One of our commonest repair jobs was changing wing tips that had been dinged on taxiing.
