So far it appears the news is reporting a cyber attack in Europe that is affecting European boarding. The RADAR/RADIO (TRACON) thing in Texas and other major airports in the US. A cyber attack on Collins Aerospace and Frontier. And some blame pointing at L3Harris for inadequate failure recovery. Sounds like no one has a clue. I wonder if any of our security apparatus is still functioning enough to provide support to find the source of the problem.
