So I'm out for a little local ILS training in X-Plane. I'm taking off to the south out of Addison (KADS) towards downtown Dallas. On take off roll I notice a large flock of birds dirfting towards the runway. Well, you know what happened next... Pictures below. Then with all the carnage out of the way I start a little practice. I'm flying ILS 15 at addision and what do you think I see on short final. Birds, this time I was able to execute a missed approach. I stayed in the pattern and landed with out incident. I parked it for the evening.
