An excerpt from
http://www.megawhat.com.au/dor_frtvc.html :
In 1963 he was aboard a DC-8 flying from Zagreb to Rijeka when an exit burst open, sucking out 20 passengers. As the only survivor, Frano was later found in a haystack suffering from cuts, bruises, and mild amnesia.
Did the above accident actually happen or is it an urban legend? I'd like to know more about the event but found no credible record of it on the net, only a string of news articles repeating the same story, with slight variations.
