The AOA is actual. To my knowledge, this is the last remaining common user of JATO bottles. Considering how many must've been made in the 50s and 60s, they're probably still going through OEM stock.
Fat Albert used the last bottles November 2009 in P-cola NAS at the Blues winter departure show.
They are looking for a replacement bottle in order to continue the C-130 portion of the show.
Hope they do!
