Two pilots and five passengers aboard an Aerogulf Bell 212 died September 3 when their helicopter crashed onto the oil drilling platform Resilient off the coast of Dubai. The crash, which occurred on takeoff from the rig, triggered a post-impact fire and caused the helicopter to break up and fall into the sea, according to Petrofac, the operator of Dubai’s offshore oil fields, and the United Arab Emirates’ General Civil Aviation Authority. An official investigation is under way.
