'Boeing Boeing,' a sometimes bumpy ride through extra-friendly skies

No thinking: that's the empty mind-set of the swinging '60s bedroom farce "Boeing Boeing," even though this peppy French artifact is fundamentally a math problem. Follow the numbers. The play is about a single jaunty playboy plus three lovely airline hostesses who jet in and out of his flat, each unknown to the other. Now consider the apartment's seven doors, brilliant white against bright blue walls in the attractive (and often breezily acted) new production at Columbia's Rep Stage.
