Son, We Flew To The Moon To Verify That It's Cheese

WASHINGTON - Doug Hardy was barely through the door of the National Air and Space Museum when he made up his first "fact."

A few days before Father's Day, Hardy and son Andrei were huddled under the Mercury capsule.

Like countless dads before him, he was explaining rocket science to his boy, in this case how the mottled heat shield protected John Glenn from a fiery death as the craft plunged through the atmosphere.

Then Andrei, 12, asked: What are these dark disks made of?

Again, like countless dads before him, Hardy answered confidently - even though he didn't have a clue.

"Steel," he said.

The shield actually is made from a plastic-fiberglass composite, said Michael Neufeld, chairman of the museum's space history division. The disks are plugs left over from post-flight analysis.

If it didn't occur to Hardy to say, "I don't know," he's not alone. The phenomenon of the "know-it-all dad" is a familiar one to the docents, curators and keepers of America's museums and zoos.

"Just about every time I'm on the floor, I hear a father say something incorrect to his kids," said Bobbe Dyke, a docent and tour guide at Air and Space for 31 years. "You can't butt in and correct them in front of the kids. You just have to cringe."

Asked about the exchange a few minutes later, Hardy, a Boston-based writer, good-naturedly admitted his lack of metallurgical expertise.

Further, Hardy confessed to winging it factwise more than once during the museum-filled road trip with his son.

"Now that I think about it, I guess I make up stuff all the time," he said.

Only a few days earlier, at the Vietnam Veterans Memorial, Andrei had asked how bronze statues were made.

Hardy finessed an explanation based on half-remembered notions of wax molds and plaster.

"It was a total BS moment," Hardy said. "But you've got to be the guy who has the answers, right? It's a habit. What should I say, that I'm 51 years old and I used to know this 20 years ago? That's not much of an answer."

Standing in the museum's entrance hall, Dyke can attach a bit of overheard blarney to just about every icon on display:

•The Spirit of St. Louis: Charles Lindbergh was the first person to fly across the Atlantic. (He was the first to do it solo and nonstop.)

•Friendship 7: John Glenn flew the little capsule to the moon. (He was the first American to orbit the Earth.)

•Sputnik: The Russian satellite carried a dog into space. (The sphere - the one at the museum is a replica of the one that went into space - is less than 23 inches in diameter.)

•The Bell X-1: The sound-barrier-busting aircraft was built without landing gear to make it faster. (The wheels are retracted.)

It isn't just dads, of course. Mothers are perfectly capable of dispensing misinformation in response to their children's nonstop queries about the world.

The howlers that are repeated with glee in museum break rooms seem overwhelmingly to feature dads getting it wrong.

"I think dads do it more because they don't want to admit it when they don't know something," said Don Lopez, the museum's deputy director. "They make a lot of mistakes."

Most of the know-it-all dads do start out with a baseline of accurate information, said Beth Wilson, a museum education specialist.

They get tripped up when they try to go too deep, she said.

"They have some working knowledge of a subject without fully grasping the details," she said. "Sometimes we say that a little PBS is a dangerous thing."
