You would have to be living in a world with no access to the radio, newspapersor tv not to hear about the recent bombing in Bali. News reports say that around 75 percent of those who died (around 200) in the blasts were Australian nationals.

But let's not forget the local people of Bali and other nationals too, who lost their lives in Bali. A further 300 people were injured in the attack. As investigations start into Saturday's nightclub bombings on Bali, Australian airline Qantas is laying on extra flights to bring tourists and injured victims back from the Indonesian island. Singapore Airlines has also been carrying additional passengers.

The United States Federal Bureau of Investigation and Australian police and intelligence services are helping in thesearch for the bombers.

The governments of Australia and the United States are advising against travel to Indonesia and the US State Department has asked all American citizens to leave the country. All US government personnel, apart from those in key positions, are being withdrawn.

The UK has also issued a travel warning, advising the cancellation of non-essential visits to Indonesia.

Despite some expected cancellations, Singapore Airlines says it is continuing to operate four daily flights to the area.

The airlines say they will not impose penalty charges on passengers who change or cancel their flight reservations. Those without tickets wishing to leave Bali are being offered discounted fares.

The US carrier Horizon Air, based in Seattle, is set to equip its entire fleet of 60 regional aircraft with defibrillators and medical kits to deal with in-flight heart attack emergencies.

Horizon is making the move two years ahead of a US Federal Aviation Administration deadline requiring any US commercial plane of at least 7,500 pounds and carrying at least one flight attendant to install the life-saving equipment.

The Malaysian prime minister condemned the new security checks on Muslim and Arab visitors introduced at US airports in October 2002.

Mahathir Mohamad labelled the new immigration rules as “anti-Muslim” and said America's stance was unfortunate. Passengers arriving in the US from Muslim and Middle East countries are now photographed and fingerprinted by the immigration authorities at all ports of entry.

In particular, nationals of Iran, Iraq, Libya, Syria and Sudan will be heavily scrutinized. Visitors from other countries, including Malaysia, who are thought to be a possible security risk, will also undergo the tougher immigration checks.

The authorities will compare pictures and fingerprints with criminal and terrorist data held by the US government. There could be a personal element here: Mr Mahathir made his attack on the system after his deputy, Ahmad Abdullah Badawi, claimed he was forced to remove his belt and shoes during a security check at Los Angeles International Airport as he arrived for a United Nations meeting.

A Beverly Hills scuba diving store has resisted a federal grand jury subpoena demanding that they identify everyone who had taken, but not finished, recreational dive classes over the last three years.

The subpoena was based upon far-fetched fears that an underwater terrorist attack could be accomplished by partially-trained divers. Apparently the FBI has already obtained information about every certified diver in the United States through the certification organisations PADI, NAUI, and SSI.

Ken Kurtis, co-owner of Reef Seekers, stated: “The scenario the FBI was painting–of divers swimming into a harbor with explosives to blow up ships–is extremely difficult and far-fetched for even the most skilled and experienced diver, and would be next-to-impossible for a newly certified diver, let alone one who had dropped out of a class and never completed training.”

We've all seen those wispy white trails that aircraft leave in the skies. Until now, scientists have been unable to calculate the impact on weather of these vapour trails. That is until post 9/11.

The grounding of flights for three days after the 11 September attacks gave scientists in the US a unique opportunity to see what the weather would be like with no air traffic at all.

They compared temperatures at 4,000 weather stations across the country with figures for the previous three decades at the same time of year. Their findings show that the gap between daytime and night time temperatures was more than one degree Celsius larger than normal when flights were at a standstill.

This is thought to be because the jet trails reflect sunlight and trap heat. That makes the day cooler and the night warmer where air traffic is heavy. However, the effect is almost certainly outweighed by the global warming influence of greenhouse gases, created by the burning of fuel including emissions from jet engines.
