I think you have convinced me to make that my next task. I think it would be more rich and actually less work using all the AI aircraft already flying at different altitudes, speeds and headings at locations throughout the world. Yeah, that would work and be fairly simple for me, other than attaching a flight path animation to a model that way. If anyone wants to create a "mission feature" for this addon, I plan to categorize the main menu and we can add the new mission category to the menu and if the new feature is modular and self contained, it will fit nicely in the scheme. I've already created an algorithm that loops through AI for the cargo towing addon. Just loop through AI aircraft in range and pic one at random then vector the interceptor aircraft to that AI for visual verification. All the information for that is already available in the property tree.
A long time ago I wrote a really small script to track an AI and try to converge or follow it.
You wouldn't have to write any code for the bogie aircraft and there are literally thousands of them out there in the FG world. Or possibly using any nearby AI commercial aircraft as the bogie would be even better. I think an AI aerial tanker re-fueling example would be a starting point for the incoming aircraft. Do you know of anything already available with any of the elements needed for something like that?
