The anecdote at the end of the article isn't that reassuring - a bad choice for an analogy IMO. If an electronic device was equivalent to a flock of geese, then with a couple of hundred passengers, many using electronic devices and some using multiple would be like 100 flocks of geese. If the evidence was that allowing electronic devices jeopardized as much as 100 flocks of geese flying at a plane during take off, I certainly would not be an advocate! Bird strikes are not trivial.
