How 9/11 Reshaped Air Travel and Banned Everyday Items
Before 9/11, airport security was less strict than it is today.
People could bring more everyday objects onto airplanes.
Some hijackers used small blades that were allowed at the time.
After the attacks, airports began checking passengers and bags much more carefully.
Sharp objects such as knives and box cutters were banned from cabin bags.
Later, rules limited liquids to containers of 100 milliliters or less.
Tools, sports equipment, fireworks, and flammable items can also be restricted or banned.
Some electronics have faced temporary limits because of concerns about hidden explosives.
These rules are designed to make airplanes safer by reducing possible dangers.
The September 11 attacks prompted governments worldwide to overhaul aviation security.
Passenger screening tightened, and authorities introduced 100 percent baggage checks for explosives.
Small knives, box cutters, razor blades, and some tools are now banned from cabin baggage.
The 100 ml liquid limit developed after initial post-9/11 restrictions and a 2006 liquid-explosives plot.
Security rules continue to evolve through scanners, screening technology, and intelligence-led restrictions.
