Update as of 05Feb2015: The series now has 17 clips with a total duration of almost 3 hours. Parts 15A and 15B are the most advanced (and the longest) as they walk the new Mission Editor user through all of the steps necessary to write a very simple mission from scratch, using the "Tutorial Text" from the editor's venerable Online Help file as a script. At the conclusion of this exercise, the viewer that follows along will have created a new "Mission Group" (Kind of a battle scenario) in a new Phillippine Islands terrain, with a single mission for two P38s that take off, fly a Combat Air Patrol over a fleet of American ships, and then return to land. No extra sound files, map images, or other media events are present yet, and only about 5 seconds are spent in the Briefing Room before the mission launches.
By applying the principles learned up to this point, a new user should easily be able to modify the route, change the aircraft type, add additional flights to fly a path parallel to the route (with a designated offset Left/Right, Up/Down, and Ahead/Behind) using different types and numbers of aircraft, and create additional Missions within the Mission Group to create a hostile encounter and resulting combat.
This gets me to a pretty good stopping point for awhile. Perhaps I may resume this project to show the specifics of how I add media events (Audio Briefing, Briefing map sequences, sound effects, and radio banter), but that will have to be postponed for awhile while real life intervenes.
