The timing wasn't just great for Bovington this year. There was quite a bit said about the Jagdpanther visiting this year, but it was having issues with steering (so it was said at least). Other tanks that I needed sounds from just didn't run, also. So, still need more trips.
Airplanes have many, many gaps as well. I do not see any way that I can continue to travel and collect sounds. It's just hitting too hard right now.
