The T-Level you see are just reported levels by people who have crafted them. These information have been there for a long time, general guideline is that if you're above T-Level 20, you should start crafting (which is why people recommended to craft at that level).

Recipe you used also has a chance (more like a decent chance) to get planes because of your bauxite, fuel and ammo usage.
