Federal Aviation Administration researchers are testing to see if smaller airplane seats can endanger passengers during an emergency evacuation, the Washington Post reports.

Why it matters: There are no federal regulations on airplane seat size, the Post notes, and this is the first time the FAA has analyzed the potential safety risks of smaller seats.

  • A record-setting 31.6 million people flew on U.S. airlines over the Thanksgiving holidays, CNN reports, citing Airlines For America.

Details: The FAA's Cabin Safety Research Team will test how quickly 60 volunteer passengers are able to evacuate a mock airplane cabin — modeled after an Airbus A320 or Boeing 737 — four different times over a 12 day period.

  • The volunteer pool does not include children or those with disabilities.

What's next: Researchers wants to release test results by next summer, FAA spokesman Rick Breitenfeldt told the Post.

The president's campaign is placing more importance on Pennsylvania amid growing concern that his chances of clinching Wisconsin are slipping, Trump campaign sources tell Axios.

Driving the news: Pennsylvania, which has 20 electoral votes, twice Wisconsin's number, actually has been trending higher in recent public and internal polling, a welcome development for the campaign.
