Very sad news.
2007 is the year that I heard. Think of how many thousands (tens of thousands?) of flight hours out of UND in the last 14 years and to have no fatal accidents until now. That's a pretty darn good safety record. No consolation for the Hauser family and friends, though.
EDIT: Turns out it's over 100,000 flight hours PER YEAR! FY2021 set a new school record of 126,000 flight hours. That's more than 1.4 million flight hours in the last 14 years.
