The plane left Juanda International Airport at 5:27 a.m. Sunday (5:27 p.m. Saturday ET) and was due to arrive in Singapore at 8:37 a.m. Sunday (7:37 p.m. ET), according to the website.
Bad weather might have been a factor in the plane’s disappearance, CNN meteorologist Derek Van Dam said.
“We still had lines of very heavy thunderstorms” when the plane was flying, Van Dam said. “But keep in mind, turbulence doesn’t necessarily bring down airplanes.”
It's that "doesn't necessarily" that bothers me.
