Hey Goa, I had someone ask me a great question but I don’t have the answer. The question was about aircraft, specifically military types, and how they are labeled. The example given was that there are a few different types of C130 aircraft (for example HC130H and HC130J) and both of these sub types just show up as C130. The question was on how to narrow down the specific type of C130, can it be done? Thanks, Jim
