I just found this in another forum:
Quoted from August letter to Customers:
"The purpose of this letter is to inform that on the morning of August 17th, 2011 an AW139 aircraft went missing into a reservoir in a northern suburb of Beijing (China), with five people aboard.
Search and rescue activities looking for the helicopter were started immediately.
AugustaWestland is working closely with the Operator and the relevant Authorities involved to support the investigation of the event."
R.I.P. anyway
