After doing some research I decided to go with the Boeing 737 grounding by the FAA. In a rush to get a new more fuel efficient plane on to the market to compete with a new Airbus model. It is reported that Boeing may have cut corners and received from the FAA a much more lenient safety certification approval. This rush in production lead to hundreds of people being killed in multiple crashes. The United States FAA was the last ground the 737. Whether it was faulty censors or lack of pilot training it is clear that all safety protocols and precautions had not been followed prior to it being released to market.
