Yikes. Unmentioned in the article, but the 737 has had some serious
control surface issues in the past.

The Transportation Safety Board is trying to find out what caused a Canadian North jet to roll, shortly after take off last December. The Boeing 737-300 had just left Fort MacKay, Alberta, with 133 passengers and 6 crew members on board. The TSB says as the airplane had climbed to about 800 feet when it began a 10 degree roll to the left. The pilots tried to counter to the right, but couldn't. Then there was a drop in air speed.
"The whole manoeuvre last 15 to 20 seconds,” says John Tavernini, a senior technical investigator with the TSB. “It wasn't very long, but it was a period of time when the pilots felt they were losing control of the aircraft. But control was regained before any upset occurred.”
