A nearly five-hour shutdown of the US aviation system was triggered by a faulty router installed by contractor L3Harris as part of a telecom upgrade from copper to fiber, highlighting the ageing FAA air traffic control communications infrastructure and the risks during its modernization.

◆ ◆ The Wire takeaway

Your telecom hardware just grounded 20,000 US flights. If you supply components or services to air traffic control upgrades, this incident opens urgent opportunities to prove reliability or fill gaps.
