CAMP LEJEUNE, N.C. (AP) _ Crews of Marine Prowler jets like the one that sliced through a gondola cable in the Italian Alps last February resented altitude restrictions that were imposed after a crash two years ago, a witness said Wednesday.

The testimony came during the second day of a hearing to determine whether the two back-seat crewmen aboard the jet, Capts. Chandler Seagraves, 28, and William Raney II, 26, should be court-martialed for the Feb. 3 accident that killed 20 people.

The two Marines and the pilot and navigator of the EA-6B Prowler face 20 counts each of involuntary manslaughter and negligent homicide. Each charge is punishable by up to 20 years in prison.

Capt. Michael George, a Prowler tactics instructor, testified Wednesday that in August 1996, four EA-6B Prowler crew members died in a crash at a Yuma, Ariz., air base.

At the time, Prowlers were allowed to perform low-level training runs at 200 feet, but after the crash, altitude restrictions were raised to 500 feet and later 1,000 feet, he said.

``Tactically speaking, you're not going to find anyone who's happy with having to make that change,'' George said.

A navigation expert also testified Wednesday that flight information recorder data showed the Prowler that cut the cable was well below the 1,000-foot restriction Americans thought existed. It was later discovered the Italian government had established a 2,000-foot limit because of noise complaints.

Chief Warrant Officer Jeff Poncelet, using a computer graphics display projected onto a screen in the courtroom, showed the altitudes at which the jet flew in a valley before the tragedy.

Eleven seconds before it hit the cable, he said, the jet was 436 feet above the ground. Just seconds before that, it traveled at 370 feet and 301 feet over a six-mile run down a steep mountain valley, Poncelet said.

Poncelet also said the map he used, identical to the one taken from the Prowler cockpit, contained a warning of an aerial cable system.

He said the map didn't show the cable's exact location, but it should have alerted the crew.

``Anytime you're in a low-level environment, you're going to be on the lookout for something that's not on your chart,'' said Poncelet, a navigator assigned to Cherry Point Marine Air Station in North Carolina. ``Here in North Carolina, it's towers.''

After this week's hearing, the presiding judge will decide whether to recommend a court-martial.

A similar hearing is scheduled June 15 for the Prowler's pilot, Capt. Richard Ashby, and navigator, Capt. Joseph Schweitzer, both 30.
