I agree UA is being unfairly singled out on these stories - the bigger issue is the fact that ATC is using 1950s technology in 2014. IMO the real question is whether the FAA will implement needed fixes before a disaster happens or if it will take a disaster to push them to implement needed changes.
The EWR is still the most worrying to me since 4L/22R remains closed for another week causing the ridiculous situation of taking off and landing from runways that intersect at one of the nation's busiest airports
