Water, along with other liquids, was banned in airports primarily due to a thwarted terrorist plot. The ban is in place to ensure the safety of passengers.
The Liquid Explosives Plot
The primary reason for the ban stems from a real security threat.
- 2006 Terrorist Plot: British authorities uncovered a plan to use liquid explosives to blow up a U.S.-bound plane. This incident highlighted the danger of easily concealing explosive materials in seemingly harmless liquids.
Enhanced Security Measures
In response to this threat, strict regulations were implemented, restricting the amount of liquids passengers could carry onto planes.
- Initial Restrictions: These rules were put in place to prevent any potentially dangerous liquids from being taken on board.
- Current Rules: Passengers are generally allowed to bring small containers (usually 100 ml or less) of liquids through security, but they must be placed in a clear, resealable bag.
- Technological Advancements:
- The technology is now available for airports to use X-ray scanners that use CT technology to give guards a 3-D image of carry-on items. These advancements may help alleviate the current ban on liquids and allow people to carry through larger amounts.
Airport Security Procedures
Below are current common security procedures related to liquids at airports:
- Limited Quantity: Passengers are restricted to carrying only small quantities of liquids.
- Clear Bags: Liquids must be placed in a transparent, resealable bag for inspection.
- Separate Inspection: These bags are often placed in separate trays when going through security.
- Specific Item Exception: Some exceptions exist for baby formula or medicine, but these items are often subject to additional screening.
| Reason | Details |
|---|---|
| Main Reason: | To prevent liquid explosives from being carried onboard. |
| 2006 Terrorist Plot | Thwarted by British authorities, involving a plan to blow up a U.S.-bound plane with liquid explosives. |
| Current Technology | CT scanners used to get a 3D view of carry-on luggage, potentially alleviating the ban, are being implemented across US Airports. |
The ban, while inconvenient, serves an important function in ensuring air travel safety. The implementation of more advanced scanning technology is expected to address these concerns going forward.
