Mad Monkey III: Smoke and mirrors

 

On December 22, 2001, a British terrorist, Richard Reid boarded American airlines flight 63 from Paris to Miami wearing special shoes packed with plastic explosives in their hollowed-out bottoms. He tried unsuccessfully to detonate the same but was overpowered by the other passengers and flight crew. After this incident (referred to as the ‘shoe-bomber incident’), the shoes came in for special screening by security staff all over the world and many countries require shoes to be taken off at the screening checkpoint. 

On September 13, 2005, a wheelchair-bound passenger, Porfirio Ramirez and his son hijacked a Colombian airliner after boarding the same at Florencia for Bogota. The weapons used were two live grenades hidden in Porforio’s diapers. After this incident, screening of sick/ wheelchair-bound passengers became more stringent; the wheelchairs were screened separately and particular attention was paid to plaster cast, prosthetics, etc.. This has created a lot of furore from genuine passengers with ailment or disability and has raised concerns about privacy issues and dignity.

 

After an extensive surveillance operation in 2006, the British Police uncovered a terrorist plot to detonate liquid explosives on board aircrafts flying from the United Kingdom to the United States and Canada. The explosives were to be disguised as soft drinks. At least seven flights were targeted by 18 suicide bombers and several associates. 24 persons were arrested in this connection in and around London on August 9, 2006. Seven of the accused persons have been convicted. This incident was followed by severe restrictions on carrying of liquids in hand baggage by several countries. Gradually, the restrictions have been relaxed and passengers are allowed to carry 100 ml containers of liquid, aerosol and gels (LAGs) up to a maximum of one litre. Liquids of higher quantity purchased in the SHA can be carried on board only if they are packed in Security Tamper Evident Bags (STEBs) by the retailer and checked at the aircraft gate. 

On June 30, 2007, a jeep loaded with propane canisters was driven at the glass doors of Glasgow airport terminal by two terrorists and set on fire, causing injury to several passengers. This incident brought to the fore the possibilities of landside attacks and has led to fixed and hydraulic bollards at the entrance to airport terminals, check posts and barriers on the approach road to the airports and permanent obstructions in front of the terminals to obstruct motor vehicles. 

On December 25, 2009, a Nigerian terrorist travelling from Amsterdam to Detroit on Northwest flight 253, attempted to detonate plastic explosives sewn into his underwear by injecting acid into it through a syringe to cause a chemical reaction. He succeeded in causing a fire and a small explosion but was overpowered by fellow passengers. Hitherto, all screening was geared towards detecting metal because it was presumed that detonation could not take place without involvement of metallic device for the charging. However, this incident showed possibilities of triggering explosions without using metal. This led to more emphasis on pat-down search and also reinforced the restrictions on liquids, aerosols and gels. 

On October 29, 2010, two packages, each containing plastic explosives hidden inside printer cartridges and a detonating mechanism were discovered on cargo planes in flights from Yemen to the United States at en route stopovers in UK and Dubai. The bombs were primed to be activated by a cell phone alarm shortly before the planes landed. Prior to this incident, security around cargo and cargo planes was lax. However, this cargo could have been trans-shipped through passenger planes also and any contamination of cargo would compromise the security architecture of the entire aviation system. This led the policy makers to tighten cargo security. Cargo was mandated to go through 100 % screening. The distinction between passenger and all-cargo aircrafts for security purposes was abolished. In India, there has been creation of cargo SHA, armed guarding of main entry and exit to cargo complexes and continuous CCTV (Closed Circuit Television) and manual surveillance of airside and Security Restricted Area (SRA) as well as city side proximate areas including car parking area. 

On January 24, 2011, a suicide bomber carried out an attack at the baggage claim area of the international arrival hall of Moscow’s Domodedovo airport killing 37 and injuring 173. India already had entry restrictions into the arrival and departure areas. After this incident, in India, ID proof was made mandatory for even visitors with entry tickets. Many airports around the world started screening and restricting entry into all areas of the airports including areas which were unrestricted earlier. 

On March 8, 2014, Malaysian Airlines flight 370 from Kuala Lumpur to Beijing disappeared after losing contact 38 minutes after take-off. The aircraft has not been traced and the 227 passengers and 12 crew aboard are all presumed dead. The security response has included mandates for increased battery life on underwater locator beacons, lengthening of recording times on flight data recorders and cockpit voice recorders, and new standards for aircraft position reporting over the open ocean. 

On March 24, 2015, Germanwings flight 9525 from Barcelona to Dusseldorf was deliberately crashed by the co-pilot while the captain was out of the cockpit, killing all the 144 passengers and six crew members. This led to regulations requiring the presence of two authorised persons in the cockpit at all times and also tightening of measures against insider threat, e.g., security vetting of all staff, 100 % screening of all staff and their baggage before entering Security Restricted Area, etc.. 

These then are the genesis of all the inconveniences one faces while travelling by air. Even so, aviation security remains smoke-and-mirrors. Actually, when good guys try to imagine bad things, they are not very good at it. Like we do our research and development, the terrorists also carry out their own R&D to find newer ways to breach the defences. Plus, they need to be lucky just once, the security guys, every single time; thus, the probabilities favour the other side. A well-informed terrorist knows that there are thousands of loopholes and building a dyke to bulwark it all would bring air travel to a standstill. So, somewhere between bluster and business, between theatre and substance, we, the security guys chug along. Literally on a wing and a prayer.
