Well, if you want to get into R & D then let me clarify........dont just limit your option for only Boeing and Airbus......most of the companies who are in manufacturing (usually the subsidiaries and partner companies of these 2 manufacturers) have their own R & D departments. After MS you can apply for Graduate Placements with either Boeing and Airbus....check their web-site....and start looking into all the companies who supply parts to these people.....who knows somebody might sponsor you for your MS depending on your academic results..... Good Luck!!!
