BANGKOK — Passengers on the Singapore Airlines flight that descended sharply after hitting severe turbulence described the "sheer terror" of the aircraft shuddering, loose items flying and people wrenched so badly that 20 remained Wednesday in intensive care.
"I arrived back in the airport and I couldn't stop vomiting. I couldn't walk, it was pretty bad," said Josh Silverstone, 24, who was discharged from a hospital with a cut in his eye and a chipped tooth. He said it could have been "way worse."
The British man said he was so scared, he bought in-flight internet access to message his mother: "I wasn't trying to scare her, but I said 'I love you.'"
Josh Silverstone of Britain, who was injured during a Singapore Airlines Boeing 777-300ER flight, talks to reporters Wednesday at Samitivej Srinakarin Hospital in Bangkok, Thailand.
Cause of turbulence unclear
It was still not clear what exactly caused the turbulence that sent the Boeing 777 carrying 211 passengers and 18 crew members on a 6,000-foot descent in about three minutes Tuesday. The flight from London to Singapore was diverted to Thailand.

Most people associate turbulence with heavy storms, but the most dangerous type is so-called clear air turbulence. Wind shear can occur in wispy cirrus clouds or even in clear air near thunderstorms, as differences in temperature and pressure create powerful currents of fast-moving air.
The U.S.-based Association of Flight Attendants said clear air turbulence is virtually undetectable with current technology. "One second, you're cruising smoothly; the next, passengers, crew and unsecured carts or other items are being thrown around the cabin," it said.
"Always follow crew instructions and wear your seatbelt whenever seated. It is a matter of life and death," it added.
