Unfortunately you need to forget about it for another number of years. As only two of the three parts are out. Part two took them four years after part one, so safe to guess the same for part three.
Also, the names are exceedingly confusing:
-
FF7 Part 1 is named: Final Fantasy VII Remake (2020)
-
FF7 Part 1 Enhanced is named: Final Fantasy VII Remake Intergrade (2021)
-
FF7 Part 2 is named: Final Fantasy VII Rebirth (2024)
If their goal is to get people to completely check out due to long, long release schedules and confusing naming, they are succeeding.
Speculation: Looks like some kid’s balloons that were showing up on radar. A interceptor was tasked to take it out, WTFed it was a balloons, then decided to complete the mission to clear up the radar return. These interceptors are not recovered, too dangerous, and it is doubtful there was another target in battery range.
Alternative Speculation: It’s a training mission for intercepts using an easy target.
