My thoughts and sympathy go out to Bingas' family, and the family of the trooper still missing. This is a tragic accident, and a reminder that we accept risk every time we fly.
I also want to acknowledge the excellence of the crews and maintainers in 171 Sqn and the rest of Army Aviation. The whole corps, and the Army will mourn this tragic loss.
Sundance 76, if the Blackhawk fleet spent even half of its time doing maritime ops, they might be fitted with floats. As it is, they spend about 5% of their time over water. Your aircraft would not have floats either if it wasn't employed solely offshore.
