    Late last year, in the weeks lead-
 ing up to 5G’s launch, the FAA and
 aerospace industry seemed to be
 scrambling to catch up. In Novem-
 ber 2021, the FAA warned of inter-
 ference, asking aerospace man-
 ufacturers to study the issue. In
 December it essentially prohibited
 aircraft – including large jets – from
 using some aircraft systems near 5G
 antennae, pending further action.
    Meanwhile, the Department of
 Transportation (DoT) and FAA
 began negotiating with AT&T and
 Verizon, which then agreed to de-
 lay 5G’s start by 30 days until 5
 January and to reduce the pow-
