AW 139
Being as the AW 139 has a VMINI of 50 KIAS, and an IFR, CAT "A" vertical takeoff not being possible due to low cloud layer or obscuration, fog, mist, etc..maybe they were attempting to build the airspeed in a CAT B takeoff profile and contacted something? Also, the blades may be damaged beyond a point of determining when they made contact with something other than air.
