“TSA confiscated my vacuum system required to fit my prosthetic legs. I told them I need those tools to put on my legs. Without them, it can’t be done. They eventually gave them back after I boarded the plane, but it would have been more appropriate to have a conversation with me about it and let me know. Had they not given the tools back, I could not have put on my legs for my entire trip. This was the worst of my many TSA experiences, but because I fly a lot, I am also concerned about the level of radiation to which I am exposed. I have had as many as 20 exposures during one trip.”
