Phillip Kennedy was chatting with his seat mate and paying no attention to the movie as he flew back to Los Angeles from New York City aboard Pan Am’s Flight 83. Then: “I happened to glance at the screen. It didn’t look like ‘Mary Poppins.’ ”

It wasn’t supposed to be. It was supposed to be “Hiding Out,” about a government witness trying to evade the Mafia by posing as a high school student. But what Kennedy and others in the first-class cabin suddenly saw on the screen was what another passenger describes as “very hard-core porno . . . very explicit.”

Someone, clearly, had inserted it as a gag.

Kennedy, who heads a Los Angeles real estate consulting firm, said “there was a hush” through the cabin as passengers became aware of it. Then, he said, the screen abruptly went blank as the movie was shut off.

The captain assured the passengers on the Wednesday night flight that the film was going to be turned over to the proper authorities as soon as the plane landed. “There was no humor or levity in his voice at all,” recalls Kennedy. His seat mate described the pilot as “furious.”

Alan Loflin, a Pan Am spokesman in New York, said Friday that the airline had not yet learned how the errant sex scene got into the movie. “The only thing we know,” he said, “is that the film cassette was delivered to us by a vendor.”

He noted that there had been no complaints from the passengers.

For almost two weeks, says Lisa Moreno, City of Commerce public safety programs aide, a rooster has been hanging out on the Santa Ana Freeway center divider beneath the Long Beach Freeway overpass. “It’s just been bopping around, having a good time,” she says.

Numerous motorists have phoned the Commerce Public Safety Department to report the stranded chicken, which has better sense than to try crossing the road. Moreno says she has called Caltrans and the California Highway Patrol, but it’s still there. “People have been feeding it,” she notes, “throwing popcorn and things at it.”

Although the rooster apparently finds shelter much of the time in bushes growing along the center strip, it was seen as recently as Friday morning by Elaine Manchester, a Kaiser-Permanente accounting clerk who drives the freeway daily on her way from Downey.

“It’s right on the edge of the road every time I see him,” says Manchester. “He comes out there to look for food. I’ve seen him every day except two since a week ago Tuesday. He worries me. I wish they’d get him.”

By popular demand, Frederick’s of Hollywood reopened the International Museum of the Brassiere at its Hollywood Boulevard store Friday. The exhibit, including bras worn by famous film stars, was supposed to be temporary when it was inaugurated last October. It was shut down just before Christmas, says spokeswoman Ellen Appel, because “we needed the space for Christmas lingerie.”

But there were all these calls . . .

This time, Appel says, the “museum” will be open through mid-June, at least.

No one seems able to explain who repaired three Whittier fire hydrants. “I haven’t a single clue, to be honest with you,” says Hal Maupin, general manager of the Pico Water District.

The Whittier Daily News reported that Assistant County Fire Chief Michael Aviani listed the hydrants as broken several months ago and asked the district to fix them. A dispute has been running for some time over whether the Fire Department or the district should do it.

Suffice to say the picture is muddled by legislation, court rulings and threatened lawsuits.

In any event, Maupin says his people examined the supposedly broken hydrants and--other than the fact that the valves had been turned off on two of them--”we couldn’t find anything wrong.”

Aviani, who was unavailable Friday, was quoted as saying the water district must have fixed them.

But Maupin insisted Friday, “We certainly didn’t.”
