Good read.
"The Independent asks how, given 21st-century communication technology, a large passenger jet can simply vanish. Since every iPad and iPhone owner can get an app that allows them to trace their device if lost, it
seems absurd that a £160m, 250-ton jet aircraft should be untraceable."

The plane can't be traced because the systems that are in place to do that were either shut down deliberately or failed at separate times for some undetermined reason.
Every time another safety factor, ELTs and/or GPS, is mentioned there is a reason given why they didn't work, aren't expected to work anyway or were of no use in the case of this plane. GPS needs a receiver to work (anything beyond that is above my head). If the systems are shut down all the locator features (expect the SATCOM, part of the ACARS, in this case) no longer worked.
It's not as if the systems to track planes don't exist, it is that someone went to great lengths to stop them from working, allegedly. Otherwise, this is a case of extreme Murphy's law where everything that can go wrong did go wrong. To include the pilots not being able to send out any kind of a stress signal to warn of the plane's failings. Also noted are the less than ideal locations at two key points during the flight, when a handoff was taking place and, if the plane crashed, near the most ominous ocean on the face of the earth. Bad luck indeed!
Not to forget, that the mother and surrounding countries didn't seem to be monitoring their radar during the hours this flight may have been in trouble. If the foreign object was observed, nobody seemed to care. Another system, if used, could have resulted in earlier investigation informing the plane was in trouble regardless of hijack or mechanical malfunction.
Also, the added safety measures of purchasing a plan related to ACARS wasn't implemented making for worst case scenario in case of a crash.
It isn't as if there aren't tracking systems in place, it is that nobody expects or expected them all to fail at once or whatever happened to make them stop working and then have every other circumstance seem counter to a catastrophic crash scenario occurring.
For the future, these systems will have to be improved and the public has the right to know what the plane they are flying on is equiped with such as full ACARS and WIFI and whatever else increases the odds of finding the plane quickly if it goes down.
For me, it is difficult to accept that all the bad luck coincidences this flight had going for it happened by chance.
