NOTAMs: Why Pay $500+ (USD) for What You Can Get for Free?
Recently, I’ve been doing research on (some) things aeronautical and learned about things like aerodome charts and ADS-B and the PPL (in Ireland) and so forth.

C#: Recursively Getting Subfolders Whilst Ignoring the Errors that Would Stop Other Traversal Means
