Jacob might have become a jet . or at least a jet is leaving the sol . Flight J, departing Alamogordo yesterday, returning the jour before yesterday, reservations taken years ago, and now you can board, up the gangplank stapled to the wing, across the wing to climb through the cockpit fenêtre , then find your way to the back of the plane, where there are serving drinks and passing out camera-guns loaded with X-ray filme for your landscape-snapping pleasure (for those who forgot to bring their own).
