Associated Press JL V V C5 V Edited by Bob Nelson Ice crystal may have caused crash OMAHA — An ice crystal in the hydraulic system of a medical heli copter may have caused it to crash * while taking off from the University of Nebraska Medical Center, a spokesman for the company that owns the chopper said Thursday. Federal Aviation Administration and National Transportation Safety Board officials are investigating the crash, which occurred just after 5 p.m. Wednesday. Pilot John Oldham, 41, and flight nurse Pete Labosky, 32, received minor injuries in the fiery crash. Both were released from the Medical Center Thursday, said hospi tal spokesman Tom O’Connor. There were no passengers aboard the SkyMed helicopter when the crash occurred. The SkyMed chopper was being moved to nearby Clarkson Hospital to allow another medical helicopter to land with a patient. The helicopter’s control stick thrust backward as the craft reached an altitude of about 25 feet, said Russ Spray, vice president of Rocky Moun tain Helicopters Inc. of Provo, Utah. Rocky Mountain owns the helicopter and leases it to a group of Nebraska hospitals. When the stick moved backwards, the helicopter nosed upward and rolled, then touched down on its tail and burst into flames, Spray said. “It was not pilot error,” Spray said. “It was like losing the power steering on your car. It may have been one of those rare occurrences when an ice crystal forms in the hydraulic sys tem.” Nebraskan Editor Mike Reilley 472-1766 Managing Editor Jen Oeselms Assoc News Editors Curt Wagner Chris Anderson Editorial Page Editor Diana Johnson Night News Editors Joeth Zucco Scott Harrah General Manager Daniel Shattil Production Manager Katherine Policky Advertising Manager Marcia Miller Asst Advertising Manager Bob Bates Publications Board Chairman Don Johnson. 472 3611 Professional Adviser Don Walton. 473-7301 Headers are encouraged to submit story ideas and comments to the Daily Nebraskan by phoning 472-1763 between 9 a m. and 5 p m Monday through Friday, The public also has access to the Publications Board For information, contact Don Johnson, 472-3611 The Daily Nebraskan (USPS 144-080) is published 6y the UNL Publications Board.

The request is expected to be sent to Capitol Hill Tuesday; the House will vote on it Feb. 3 under an agree ment between the White House and the Congress last month. To increase the prospects for con gressional approval, Reagan said Wednesday that less than half of the request will be for military equip ment. “The majority of the aid that I will be requesting from Congress is for non-lethal assistance to keep the free dom fighters a viable force until democracy is irreversible in Nicara gua,” Reagan told a group of backers at the White House. Supporters and opponents agree that the vote is likely to be extremely close, with the outcome hinging on about 50 House members who could decide either way.

Hart denies allegations of illegal contributions WASHINGTON — Gary Hart denied Thursday allegations of possibly illegal campaign contributions, while his Democratic rivals sharpened their rhetoric on the budget and taxes. Hart, in New Hampshire, spent most of Wednesday answering questions about a newspaper report that his campaign had accepted aid that skirted federal limits on contributions. Asked Thursday about further details provided by former staffers, he said, “No, no, it’s not true.” In Iowa, meanwhile, on the day after the Democrats’ second debate in a week, Rep. Richard Gephardt of Missouri continued the sharp rhetoric that has marked recent Democratic discourse.

Israel eases curfews on Gaza strip refugee camps JERUSALEM — Israel eased curfews on some Gaza Strip refugee camps so Palestinians could go to work Thursday, and assigned more police to an Israeli highway where Arabs threw firebombs at a school bus. The bombs missed the bus and did not explode. A visiting Red Cross official said there appeared lobe no critical food shortages in refugee camps under curfew, which supported the Israeli position. U.N. officials who administer the camps in the occupied territories challenged his statement. Defense Minister Yitnak Rabin’s decision to have soldiers beat protesters instead of firing on them brought this comment from the State Department: “We are disturbed by the adoption of a policy by tiie government of Israel that calls for beatings as a means to restore or maintain order.” Millions in USSR to be laid off in next 12 years MOSCOW — About 16 million Soviets will be laid off by the year 2000 under Mikhail S. Gorbachev’s reform drive, and some people are already worrying about a return of mass unemployment, Pravda said Thursday. The account in the Communist Parly daily gave more hints of the widespread concerns raised by Gorbachev’s drive for “percstrioka,” or the wholesale revamping of the Soviet economy and society. Along with a more effective use of the labor force, the Soviet Communist Party general secretary has said an increase in retail prices is needed to pay the real cost of producing milk, bread and other food staples and reduce the $97 billion the government pays in annual subsidies. $ Turn Extra Time Into Extra Cash $ t C T Earn $115 your first month plus bonus cash do- j 5 nating plasma.
