These threats against aircraft are likely to continue. Now it is up to the authorities to decide how they want to respond.
As I said yesterday, there are two risks: either authorities scale back inspections and security measures, potentially allowing a genuine threat to go undetected, or they continue treating every threat seriously, with all the disruption and costs that come with it.
Regardless, whoever is behind this has identified a vulnerability and is exploiting it. I also wouldn't be surprised if more individuals or organisations become involved as this tactic spreads.
Also, whatever the objective may be, whether it is a state actor, an organisation or individuals behind these threats, the effects are largely the same: eroding public trust in institutions, creating chaos, disrupting critical infrastructure, generating economic losses and putting authorities under constant pressure.
The ultimate impact goes beyond aviation. It creates uncertainty, fear and the perception that authorities are unable to protect essential services.
