Trapped in a world where obsessions and desires must be fulfilled. Dynasty, Tuesday 9.30, right after All the Way on Channel 9. Good evening, I'm Heather Ford. Guards at New South Wales' Goulburn Prison have averted what could have been the biggest mass escape in the state's history. A thorough search yesterday uncovered homemade keys to nearly every door in the jail. Some were even able to unlock gates at other high security institutions. It was in Goulburn's new industrial wing, due to open tomorrow, where the first discovery was made. A variety of knives and forks and smoking implements. Prison officers who'd been involved in a mock hostage exercise then searched the main jail. There they found a quantity of white powder believed to be heroin, parts of a walkie-talkie radio stolen from prison guards a few months ago, and a substantial number of keys. Prison's Minister Michael Yabsley says the keys, fashioned from aluminium and plastic, would have opened almost every door within the jail, including the high security section. That would have amounted to a massive breach of security involving tremendous implications for the collective services and would have involved a mass escape. But the discovery went far beyond preventing a major breakout at Goulburn. It also uncovered a number of master keys thought to fit other maximum security jails in the state. Prison authorities believe key blanks were covered in putty and then placed in locks to obtain a precise pattern. Prisoners going to elaborate lengths to conceal the end product. Some of the keys were found inside sealed cornflakes packets, inside margarine in the containers, and various other places that prisoners used to secrete items. Further search of Goulburn last night uncovered implements for making the keys, including metal files, putty and hacksaw blades. Authorities say the discovery averted what was potentially the most serious situation ever faced by the New South Wales prison system. The Soviet hijackers who yesterday surrendered to Israeli officials have now flown home to face the music. Israel only agreed to hand over the gang to the Soviets after Moscow gave a written assurance they would not be hanged. Star hijacking began two days ago in the Soviet Union with the abduction of a busload of school children. The hijackers exchanged their young hostages for a huge ransom and a plane which flew them to Israel. After surrendering themselves and the $2 million ransom to Israeli officials, the hijackers spent the remainder of their time abroad in a Tel Aviv jail. That was until the arrival of a plane carrying 19 Soviet security officers and doctors. Under heavy police escort, the four men were handed back one by one to the Soviets. Air piracy is a capital offence in the Soviet Union, but the hijackers will not be executed. Israel made sure of that. To circumvent the lengthy extradition process, the hijackers were deported as illegal aliens, simply as people who'd arrived without a visa. The bags of money were returned to the Soviets, and Israel, pleased with its handling of the incident, is optimistic there will now be a greater understanding between the two countries. Air traffic controllers seem to agree. It was a pleasure for us to assist you and hope to hear from you soon. As for the 30 Soviet children, they were reunited with their families, and their story of terror was told on Soviet television. The reporter conducting the interview held up shell casings that during the 22-hour-old deal, the hijackers had fired into the air. At one point, they exchanged five children for narcotics. We were told, said one child, if we panicked, something awful would happen to us. Australian tailender Jeff Lawson has been taken to hospital after being hit in the face in the second test at the WACA. Lawson was struck a stinging blow from a fiery delivery by fast bowler Kurt Lee Ambrose. The Australian was taken from the field on a stretcher and rushed to hospital with a suspected fracture of the cheekbone. Australian captain Alan Border immediately declared at 395. The West Indies in their second innings were won for two, with Merv Hughes strapping Greenwich LBW completing a hat trick. America has clinched the world barefoot water ski championships held on the Yarra River in Victoria. 13 nations competed, but a neck-and-neck struggle for supremacy between America and Australia was the highlight. With a slender margin separating the two countries, the tricks event would decide the winner, and Australia seemed to be keeping their best until last when Canberra's John Penne skied a personal best. Penne has won as several skiers to undergo a random drug test. Samples will be sent to London to be analysed. Skiing in difficult conditions, Australia's Gavin O'Mahony fell on his second run, but the rolling water also proved disastrous for dual world champion and doyon of the sport, American Mike Seipel. But it was 18-year-old Rick Powell who came to the rescue. This world record performance earned him the overall champion title, and America the team's championship. Weather now, fine, and a temperature range of 18 to 29 degrees. That's Nightline for this week. I'm Heather Ford. Good night.
