Chinooks can do a near zero groundspeed EOL....it takes a bit of practice to get it down to that.

Our standard EOL was a 180 degree although we did do a lot of 360 overhead EOL Landings,....which started about 2,000 feet AGL.

One should recall that the vast majority of our descents to field sites were with the Thrust Lever (Collective) full or. nearly full down and included steep turns until reaching 250-300 feet AGL then regaining power and a standard steep approach angle.

That limited the exposure time to ground fire and made the aircraft a harder target to hit and allowed you time enough to deal with a Single Engine failure of any kind.

In a one year tour where you flew a thousand hours or more you had plenty of practice to get it right.....and that translated to being able to do better touch down EOL's.

But you are right....run on at 60 Knots....and you better be at London Heathrow sized runways as aerodynamic braking only works to slow you down and upon getting all four gear onto the ground you are still moving at a fair ol' pace.
