It’s 10 O’Clock — Plus Five Hours, Greenwich Mean Time — Do You Know Where Your Children Are?

Impressive . . . and rather dramatic:

A London teenager ran away from home, crossed the Atlantic, and was missing in New York last night, police said.

George Lenon, 17, got into an argument with his parents, Sheila and Andrew, at their home on Monday, according to authorities. He headed for the airport and hopped on a plane, using a ticket he purchased with his own money, law-enforcement sources said.

He arrived at Kennedy at 9 p.m. Monday and later cleared customs.

On the customs form he filled out at the airport, he indicated he was planning to stay at the Alexander Hotel, on the Upper West Side.

Police said that they did not know whether the youth ever arrived at the hotel on West 94th Street, which caters to young foreign travelers, particularly those from England.
