WARNING: Some viewers may find the photos in this story offensive

OKANOGAN COUNTY, Wash. – Officials with the Naval Air Station Whidbey Island said one of their aircraft was involved in obscene skywritings spotted in Okanogan County.

Photos sent to KREM 2 by multiple sources show skydrawings of what some people are saying is male genitalia. Some sources have even tweeted pictures of what they saw.

A mother who lives in Okanogan who took pictures of the drawings reached out to KREM 2 to complain about the images, saying she was upset she might have to explain to her young children what the drawings were.

In a statement to KREM 2 News navy officials said, "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."

KREM 2 spoke to the Federal Aviation Administration to get some information about who may have made the drawings. FAA officials said unless the act poses a safety risk, there is nothing they can do about. The official said they "cannot police morality."
