According to the last order by Federal Aviation Administration—issued on December 10—BAASS is now the organization to contact if you are a pilot or an air traffic controller who gets close to an Unidentified Flying Object:

“Persons wanting to report UFO/unexplained phenomena activity should contact a UFO/ unex­ plained phenomena reporting data collection center, such as Bigelow Aerospace Advanced Space Studies (BAASS) (voice: 1-877-979-7444 or e-mail: Reporting@baass.org)”
