Aviation security expert and INFORMS Fellow Sheldon Jacobson provided insight on vulnerabilities at airport checkpoints, like the kind that resulted in 11 passengers passing through an unsupervised checkpoint at JFK airport in February, all of whom reached their flights without further screening.
“The most vulnerable time for any kind of check point is in a transition period,” said Jacobson, who continued that airport security is weakest early in the morning and during shift changes.
