BERLIN (AP) _ Prince Charles called Princess Diana the British army's ''most glamorous colonel'' as the royal couple began a weeklong West German visit amid press speculation at home that their marriage is in trouble.

Charles, 38, and Diana, 26, smiled and waved Sunday as they stepped off their plane. They were greeted by West Berlin Mayor Eberhard Diepgen and then went to city hall for a reception.

''My wife is the most glamorous colonel in the British army,'' Charles said while he and Diana were shaking hands with some people in the crowd.

Diana has the honorary title of colonel-in-chief of the Royal Hampshire Regiment, which has units stationed in West Berlin. The princess smiled at her husband's comment.

Their itinerary called for visits to Bonn, Cologne, Munich, Hamburg and Celle.

ELAT, Israel (AP) - Sylvester Stallone laughed off a close call he had with a helicopter on the set of ''Rambo III.''

''I suppose if it had gotten any lower I could have saved the cost of a haircut,'' production spokesman Tom Gray quoted Stallone as saying Sunday after the helicopter missed his head by a few inches. Stallone ducked just in time and escaped unharmed, Gray said.

Gray said the scene called for a French-made Puma helicopter to buzz Stallone as explosives went off and fire flared around the actor.

Gray said the pilot was supposed to fly the copter about 6 feet above Stallone's head but misjudged the distance because of dust and flames.

Rambo III is scheduled for release in the summer.

MIAMI BEACH, Fla. (AP) - Guitarist Ron Wood, joined by ''Miami Vice'' television star Don Johnson for a showing of Wood's artwork, is keeping busy without the Rolling Stones.

''I give it a couple of years before we work together again,'' Wood said Sunday of the Stones, the venerable rock 'n' roll band he joined more than a decade ago. ''But I'm very hopeful about that.''

With star singer Mick Jagger highlighting his solo career, the Stones aren't providing any work for Wood.

Wood displayed his woodcuts, etchings, charcoals, watercolors and silkscreens at the former Arlington Hotel, which will open with a musical performance by him in mid-December as the oceanfront ''Woody's On The Beach.''

His drawings depicted celebrities, mainly rock stars. There was a sketch of Johnson, who made a quick appearance, at the head of the display. Wood played on Johnson's 1986 album.

ESTES PARK, Colo. (AP) - Explorer Will Steger, who completed a dogsled trip to the North Pole last year, is now aiming to reach the South Pole by the same method.

Steger will make the official announcement of the 1990 Antarctica expedition Dec. 1 in New York, he said Saturday at a meeting of the Explorer's Club, an international group of several thousand adventurers.

The stakes are high, he said. ''Your travel in the Arctic or Antarctica is almost literally on your hands and knees,'' he said. ''It's a very humbling environment.''

''You have to make your life out of it. And it's a great thing to dedicate your life to,'' the 43-year-old Minnesota native said.

In addition to himself, the Antarctica expedition will include a Russian, an Englishman, a Canadian, a Japanese and a Frenchman, he said.

The international roster is aimed at raising awareness of environmental and political concerns that Antarctica will pose to the world in the near future.

FOXBORO, Mass. (AP) - Kansas City Royals outfielder Bo Jackson was modest as he earned praise from his coach in his professional football debut.

The Los Angeles Raiders' rookie running back ran eight times for 37 yards in the Raiders' 26-23 loss to the New England Patriots on Sunday. He suited up for his first NFL game the previous Sunday but didn't play.

''I thought Bo did pretty well for his first time,'' Raiders Coach Tom Flores said. ''He showed some explosion.''

''I just went out and played. Nothing special,'' Jackson said. ''It's fun to play any sport on the professional level.''
