An alleged cyberattack targeting a company that manages check-in and boarding systems for airlines caused delays and cancellations at Europe’s busiest airports on Saturday. Passengers were left stranded at Heathrow, Brussels, and Berlin airports following the reported cyberattack on Collins Aerospace, an American aviation company headquartered in North Carolina.Passengers stuck at the airports reported long delays and said they had received little information regarding the reported attack. Do you think that manual systems should be available as a backup ?
