 Six days before the shooting. ABC's Pierre Thomas. Airports are slowly getting back on track, but they're still a mess after Friday's global cybersecurity outage caused by a software glitch from the IT company CrowdStrike. More from ABC's Morgan Norwood. CrowdStrike says that they are committed to transparency and that they plan to share with customers how this happened and steps to prevent this from happening. If you are traveling, if you'd like to avoid the chaos, it's best to check with your airline before showing up here to the airport.
