FYI this was the first actual shutdown on the EMB fleet. THAT IS A FACT. there has been some high vib issues which required some air turn back. The fact we have these aircraft and if they are suitable is one thing but constant slandering of an aircraft that flys all over the world with many legacy carriers is getting comical. From memory I can remember 2 320 shutdowns in the past year and no one wants to complain about that. Facts is when u fly aircraft sometimes things happen. Thats why we are there. I think.
