In case there was any doubt, the US Navy has confirmed that there is “zero training value” in drawing penises in the sky.

Navy officials were faced with an unusual controversy after residents of Okanogan County, Washington, noticed a sky drawing many said looked like male genitalia on Thursday.

“US Navy air crew, flying an F/A-18 Growler (Electronic Attack Aircraft) assigned to Electronic Attack Squadron 130 based at Naval Air Station Whidbey Island, Wash., flew an air pattern over Okanogan County, Washington, on Thursday, November 16, that left a condensed air trail resembling an obscene image to observers on the ground,” Navy spokesperson Lt. Cmdr. Leslie Hubbell said.

Several individuals also took to social media to post photos of the phallic drawing.

One mother told news outlet KREM 2 in Spokane that she was upset that she might have to explain to her young children what the images were.

“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,” a statement from the Navy air station said.

“The actions of this aircrew were wholly unacceptable and antithetical to Navy core values. We have grounded the aircrew and are conducting a thorough investigation – and we will hold those responsible accountable for their actions,” Hubbell added. “The Navy apologizes for this irresponsible and immature act.”
