The Blackhawk also has a very hefty main undercarriage. As I recall (but it's a few years since I was current) it can withstand about 500 feet /minute landing without damage; which equates to the rate of descent for an instrument approach without flaring at the bottom.
One of Mr. Sikorsky's best ever products, if not THE best one, imho.

Er... The pilot?
