My first thought after watching several news articles is one of disbelief. Why would you have a tracking system in a plane that can simply be switched off. Surely it shouldn’t be possible to switch it off or there should be a backup tracking system that comes on if the main one is accidentally switched off or damaged. It’s like having a car with a steering wheel that can fall off. Don’t they have a brain? My prayers go out to all the people and families of those who were lost from this tragic flight. What do you think?
