I don’t know what KCM is neither am I a commercial pilot but I do want to chip in regarding TSA not knowing their sh**. Flew from ATL to PHX. Morning flight from ATL, I give TSA my Canadian drivers license, no problem. Then, same day in the evening in PHX, I give TSA that same drivers license, suddenly it’s “sorry, we don’t accept Canadian drivers license”. I told him that he must be wrong because TSA in ATL had no problem with it. He insisted they’re wrong, he’s right. No problem, I always have my passport on me anyways, so I gave him that and he let me go. As I was standing in line to get x-ray’d, I see another TSA officer was taking to the officer I saw. Then the officer came to me while I was waiting apologizing, saying that Canadian drivers licenses are an acceptable form of ID. He just didn’t know but got “re-trained” on that as his supervisor accidentally overheard our conversation. At least he admitted to having been wrong.
