It is nothing short of negligent that this information is easily read on the flight recorder after the crash but was not accessible to the crew.
That's what I said earlier. I read somewhere that AoA display is/was an option on certain Boeing products, not sure about Airbus. It would be sickening to know that, in those dire moments, the single most important parameter, while present and available to the system, wasn't displayed because the customer had't ordered the software feature to do so.
