United States Navy officials admitted members of the organization drew what some perceived as obscene images in the sky in Washington this week.  The incident was discovered after viewers sent multiple pictures to KREM-TV in Spokane showing skywriting of what appeared to be male genitalia.

Some residents in Okanogan County said they were offended by the images shown in the sky and complained that they had to explain to their children what was happening. At least one person tweeted an image of the skywriting, calling it “the most monumental thing to happen in Omak.”

Officials from the Naval Air Station at Whidbey Island said one of their airplanes was involved in the incident, according to KREM.

“The Navy holds its aircrew to the highest standards and we find this absolutely unacceptable, of zero training value and we are holding the crew accountable,” an official told the station.

Officials from the Federal Aviation Administration, however, said even if the incident took place, there is nothing they can do about it. The FAA said if they act did not pose a safety hazard, they “cannot police mortality,” according to KREM.

The Naval Air Station at Whidbey Island touts itself as the “premier naval aviation installation in the Pacific Northwest.” The base contains four P-3 Orion Maritime Patrol squadrons and two Fleet Reconnaissance squadrons flying the EP-3E Aires, its website said.
