According to the board's spokesperson, Chris O ' Neill, one of the areas which are going to learn what the NTSB investigators say, when it would have been possible to prevent a crash if the ship had been fitted with electronic devices. Automatic emergency braking is definitely something that we'd like to take a look at," he said.

Back in 2015, the NTSB recommended that the manufacturer of the integration of electronic safety systems as standard equipment.
