Scary situation on rooftop-helipad

[170']

If it was GR? (impossible to tell from a video; as it only shows up clearly on video when it's pretty much passed the recovery stage) quick action on the part of the pilot prevented this becoming far more dramatic... My own choice on an elevated helipad would also be to take it airborne rather than try to shut it down quickly (being shaken off the roof with engines spooling down and rotor brake coming on doesn't appeal much

I can easily imagine him looking back to check how the unloading is going and experiencing a skid settling,incipient GR event, and struggling to get into a normal seating position and fly the machine off at the same time...Just supposition on my part...

Looks like He did an good job to me...
