It sounds like a faulty indicator in the cockpit. That's actually pretty common. My father was in the USAF for 30 years, and in that time he saw
exactly ONE airplane come back with a fire warning light in the cockpit, and an actual fire in an engine.
Two more today. A plane flying to California landed with a crack in the windscreen, no one was hurt, and they moved to another plane and continued the
flight.
Quantas made an emergency landing in Japan after a false alarm. They received a warning light in the cockpit of smoke in the cargo hold, landed and
evacuated on the slides. A few minor injuries.
At the very least no one can deny that theres been a lot of REPORTED plane crashes/near misses these last few weeks. Now for all I know this type of
thing could have been happening every day for the last 20 years, but it seems to me to be getting unnaturaly common, at least when browsing the News.
Whenver there is one crash the media will go out of their way to report on every other incidence they can to try and develop a "connection" and to
fill up news time. I seriously doubt there is any conspiracy but rather just more attention.
Same thing happens with freeway shootings in Los Angeles. The reality is they happen every year and yes people get killed. The only difference is when
you have one high profile event that gets coverage then the other stations all scramble to get the first dips on coverage for other events and it gets
blown up like this is an abnormal amount of road rage going on. Or that like in the case of the "sniper" that you have a malicous element in society
that is causing this all of a sudden.
When it has been happening all along and the media has just decided at this point in time to make a circus out of it by covering every single
incident.
