I was thinking they could actually give us the Betty bomber, with the Baka loadout option. Pilot would be responsible for getting the Betty to within launch range, then, upon launch, the Baka, now controlled by the pilot, would rocket away from the Betty. Once it was far enough away, the Betty would explode, just like a runaway drone, leaving the Baka under the pilot's control.
While spawning them at 20k at PT spawnpoints is definitely simpler, I'm afraid itmay be just a bit too easy. It also seriously restricts the useability of the Baka to certain areas. CVs that stray into these areas, on the other hand, are bound to be inundated by wave after wave of bakas.
With my option, the pilot would actually have to demonstrate some skill/luck, by getting the mother plane to within launch range. After that, whatever happens, happens.
