Susie , boots, from what I been told is almost impossible to prove without paperwork. From Travis Our flight stopped in Hawaii for fuel then direct to Thailand. You can use buddy letters but they have to have prove also. Most thai vets now are using exposure to herbicles NOT agent orange. Only problem is , your mos must show you worked on or near flightline everyday. Look up on the web "VA CP Bulletin May 2010 " for herbicle exposure in Thai.
