That's Black Hawk, not Blackhawk. The Blackhawk was the S-67 gunship.
The Black Hawk is the S-70/UH-60.
The tail of the Blach Hawk was designed originally to allow the
helicopter to be flown home without a tail rotor. However, the large
fin created too much tail rotor blockage and had to be trimmed back,
resulting in the "missing tooth" tail we see today. I don't think that
the Black Hawk has the capability to fly home after loosing the tail rotor.
To quote USAAVRADCOM-TR-82-D-26 "Directional Control Developmental
Experiences Associated with the UH-60A Utility Helicopter" on page 66;
"It was eventually accepted that no fly home capability existed."
