Though aviation marked its 100th aniversary it seems we still only learn painfully from event to event and continue to follow on Murphy's track.
This sucks. - Big Time!
Now, after this obsulete midair we finally get more precise ICAO standarts dealing with TCAS. So when will all aircraft be equipped with such a life saving device, which clearly proved it is worth its pricetag on numerous occasions in daily operation?
Probably we will sooner see all automobiles equipped with similar distance alert systems, as we have seen airbags becoming standart there, then it would become mandatory for anything flying to have TCAS on board and functioning at all times.
The really sad part here is the murder of the controller. But maybe it will mark another 'wake up call' for those, specifically in charge of decisionmaking and implementation in safety relevant areas, so that one desperate husband or wife won't wait in front of their door, after a fatal accident entirely wiped out another family.
Times are getting more violent these days, and this may happen everywhere, anytime.
