The Aviation Herald is reporting that the European Aviation Safety Agency is about to issue a safety information bulletin about high-altitude wake turbulence after a Challenger 604 business jet was written off after flying 1,000 feet below an A380. According to the Aviation Herald, the incident happened Jan. 7 over the Arabian Sea. The vortices from the Emirates super jumbo jet reportedly caused the big business jet to roll three to five times as it went out of control and lost 10,000 feet before the pilots wrestled it under control and restarted the engines. The Challenger headed for an emergency landing in Oman and there were serious injuries to some of the nine people aboard. The G forces on the airframe damaged it beyond repair.
