Thanks waffler,
I wonder why this reason is not reported in the IT ?
Either they didn't know, or they wanted people to think it was a matter of life or death, plummeting to the ocean, narrowly missing the schools etc on the way down.
To be honest, the way the media ridiculously and needlessly hype up the most minor of events in the aviation industry, it's not paying much attention to. 9 times out of 10 its something abnormal, but not serious
