Problem: Airport construction boomed during the 1960s with the increase in jet aircraft traffic. Runways were extended out to 3,000 m (9,800 ft). The fields were constructed out of reinforced concrete using a slip-form machine that produces a continual slab with no disruptions along the length. The early 1960s also saw the introduction of jet bridge systems to modern airport terminals, an innovation which eliminated outdoor passenger boarding. These systems became commonplace in the United States by the 1970s.
Why did airport construction boom during the 1960s?

Input: Separation of church and state in the United States
In 2002, a three judge panel on the Ninth Circuit Court of Appeals held that classroom recitation of the Pledge of Allegiance in a California public school was unconstitutional, even when students were not compelled to recite it, due to the inclusion of the phrase "under God." In reaction to the case, Elk Grove Unified School District v. Newdow, both houses of Congress passed measures reaffirming their support for the pledge, and condemning the panel's ruling. The case was appealed to the Supreme Court, where the case was ultimately overturned in June 2004, solely on procedural grounds not related to the substantive constitutional issue. Rather, a five-justice majority held that Newdow, a non-custodial parent suing on behalf of his daughter, lacked standing to sue.

Why was the case of Elk Grove Unified School District v. Newdow overturned?
Output: procedural grounds
