Airport security theatre is painful.

Astonishing to me is the inefficiency and, often, public humiliation of people like sheep having their bags and bodies examined at the security check.

Heathrow Airport has the best system I’ve ever seen.

It’s obvious the trays have to be a conveyor belt. Empty trays are shuttled back to the start on the lower level.

Why don’t all airports buy these?

Departing Heathrow for India. Right now.
