Anecdotally, Airbus CEO Thomas Enders told the Paris tabloid "Le Parisien" that "We are studying other ways of collecting flight data... For example, the most important data could be sent out over a satellite link in real time, as is already the case with maintenance data. We're working on this with our partners and suppliers."
Le Parisien also quotes blackbox inventor Pierre Jeanniot as saying the recorders were "obsolete" and "new technologies are available."
