Both studies, published in the British Medical Journal (BMJ), found that people living with the highest levels of aircraft noise had increased risks of stroke, coronary heart disease and other cardiovascular diseases.

Cape Town - All international flights leaving Cape Town International Airport after sunset are being escorted by security patrols before take-off, airport communications manager Deidre Davids says.

This was part of security improvements after an intruder scaled the airport fence last Wednesday night and was found dead inside the landing gear of a British Airways plane at Heathrow the following morning.

“Additional security measures include a security escort of all international flights after dusk. This means international flights will have a security patrol vehicle driving behind them, with a clear line of sight of the undercarriage. We have also strengthened the security presence on the perimeter fence.”

Police spokesman Dennis Adriao said the stowaway had still not been identified. “The Department of International Relations is working on getting the body returned.”

Department spokesman Clayson Monyela could not be reached.

British Airways spokesman Stephen Forbes said: “I don’t have any update. My understanding is that the Metropolitan Police was called and they then opened a case. They will then be liaising with the SA police. That is what I understand.” - Cape Times
