I am also pretty sure from my readings of Aviation Herald that dozens of incidents happen every day. Few result in anything beyond a sensationalist headline and a few lines on twitter.
So yesterday September 20 2013 an incident occurred almost directly over my head. About 38,000 feet over my head actually. That is about eleven and a half kilometers - up!
I saw it happen not in the air but on Twitter a short while later. You have probably seen the headlines that 2 Qantas planes almost crashed over Adelaide.
I'd like to tell you how I followed up what had happened and the tools I used to discover the truth.
