Swiss authorities have just held a news conference where it was confirmed all 20 aboard (3 crew, 17 passengers) were killed in the crash.
HB-HOT (c/n 6595) was delivered to the Swiss Air Force in October of 1939 and served until 1981. She was transferred to JU-Air in October of 1982 and returned to airworthiness in 1985.
She was also famous for depicting the aircraft that dropped Clint Eastwood and his men in the 1968 war epic "Where Eagles Dare", and more recently depicted the Luftwaffe Ju-52 in the 2008 war movie "Valkyrie".
