Ridge’s report, though, neglected to note that other N.F.L. stadiums are near airports, including MetLife Stadium, the home of the Jets and the Giants, which is a few miles from Teterboro Airport and Newark Liberty International Airport. (Planes have also banked around Citi Field on their final approach to La Guardia Airport.)

Nevertheless, AEG paid Mark Rosenker, a former chairman of the National Transportation Safety Board, to write another report on the potential of accidental threats from laser pointers, drones, stadium lights and even equipment falling off planes. The blimps and small planes pulling banners around stadiums on game days could also be affected by the wake from wide-body planes heading in and out of the airport, he said.

“Why potentially site an 80,000-person stadium right near the third- or fourth-busiest airport and not expect there to be some risks?” Rosenker said in an interview. “Is it the only place in the Los Angeles metropolitan area where you could build such a building?”

Eric Grubman, who has worked closely on developing the Los Angeles market for the N.F.L., said that the league had a lot of experience with overflight risk, ingress and egress, and design and construction of stadiums, but that it would most likely rely on outside experts if the project in Inglewood progressed.

The Rams, as well as the Raiders and the Chargers, have been in contact with the league about their plans, but the league will begin a formal review of their proposals only if one or more of the teams applies to relocate.

“We’re spending time on any site which could conceivably host a team, but we spend more time as the probability increases,” Grubman said. “Now that the Inglewood site is entitled and Carson is along that process, we’re spending more time looking at them.”

Russ Stanton, a spokesman for Kroenke and Stockbridge Capital Group, which proposed the stadium in Inglewood, declined to comment on the findings of the reports. Michael Roth, a spokesman for AEG, declined to comment on why the company commissioned the reports.
