In the 1960s the average number of killed were 13 per year, which meant Sweden had sixfold mortality rate per 100,000 flight hours compared to the United States. In the 1960s flight safety starts to become a consideration, not due to the death toll but because the aircraft were getting increasingly expensive. In October 1960, a Lansen fighter crashed into a farmhouse and killed 7 people. In the 1970s the death toll was reduced to 6–7 per year. In subsequent years, it continued to fall and from 1996 onwards, no fatal accident has been recorded.
