We at Crocodile have often recounted how strong and durable the Mountain Buggy stroller is. Here is another instance of its strength:

Recently, a building collapsed in uptown Manhattan. The report from the New York Times said that people on their way to work rushed over to see if anyone had been trapped and ''When we cleared the debris, there was a mother screaming, 'My baby! My baby!'...

They found the baby girl's nanny; Brunilda Tirado, 56, who had tried to shield her charge, Abigail Lurensky, 7 months, from the cascading bricks and wood.

The crowd of construction workers and neighbors pulled Ms. Tirado free, her arms covered in blood, and kept going. Finally, the crowd lifted a steel beam high enough for one construction worker to climb into the wreckage on his hands and knees. The worker, Alfredo Ramos, 50, found her still in her Mountain Buggy Urban Double Stroller, that had collapsed but quite possibly shielded her from the debris. She wasn't crying or moving.

''I touched her arms and legs, and she was warm,'' he said. ''The steel beam was about two inches from its face. I pulled the baby out.''

Jesus Palacios, 31, a paramedic at St. Luke's-Roosevelt Hospital Center, said Abigail was covered in dust and was blue and not breathing when he got to her at the site. Speaking at the hospital later, he said that he and his partner, Michael Blecker, 23, had tried to revive her but that she did not respond until they were on the way to the hospital, when she recovered her color and started crying. ''I think she'll be O.K. because of the way she was responding.''

The next day the New York Times reported: It is impossible to say with certainty that the Mountain Buggy Urban Double Stroller actually saved Abigail Lurensky, 7 months old, as a Manhattan building collapsed around her on Thursday.

But it didn't hurt.

Alan Jurysta, president of Sycamore Kids of Denver, the exclusive U.S. importer of the strollers, observed that the structure of the Urban Double is sound. The frame of the stroller is made of a single piece of aluminum alloy, and the design resembles the strong A-frame of a house, he said.

Joan Muratore, the Consumer Reports researcher who tests strollers and other baby products, said the seat-belt system of the stroller might have been more important than the frame. ''It may have held the baby in as the debris fell,'' she said.

Whatever the case, Mr. Jurysta and Tritec Manufacturing of Lower Hutt, New Zealand, the maker of the stroller, are elated at the publicity. (They have also made arrangements to replace the stroller for the Lurensky family.)

Jesse Muru Paenga, the chief engineer for Tritec, Mr. Jurysta said, was ''just over the moon that they saved the baby.'' He also asked Mr. Jurysta for a favor. When city agencies like the Buildings Department complete their investigation, Mr. Jurysta would like the crumpled Urban Double so he can send it to New Zealand for research. ''Jesse thinks it's quite an engineering challenge and wants to see if some design improvements might be possible,'' Mr. Jurysta said.

And then? ''They're thinking of putting it in the company museum,'' he said.
