Residents were variously shocked and entertained to see a navy aircraft drawing a gigantic cloud member. The navy has since apologized for the stunt.
The US Navy apologized on Friday after one of its aircraft drew an enormous penis in the sky.
Residents of Okanogan, Washington, were alarmed to see a crude phallus drawn in a sky-writing manner on Thursday. People shared images of the penis on social media.
One mother reportedly reached out to local broadcaster KREM to complain about the celestial artwork, saying she struggled to explain it to her children.

Many locals seemed to see the funny side though. Ramone Duran told local broadsheet The Spokesman Review he saw a plane spend about five minutes making the giant member.
"After it made the circles at the bottom, I knew what it was and started laughing," Duran told the paper. "It was pretty funny to see that. You dont expect to see something like that."
Local bartender Misty Waugh told the paper her 12-year-old son sent her a picture of the aerial johnson.
"I thought it was pretty funny, and so did he," she told the paper. "A lot of people have been talking about it."
The navy later released a statement apologizing for the stunt, in statements to KREM and Fox News.
"US Navy air crew, flying an F/A-18 Growler (Electronic Attack Aircraft) assigned to Electronic Attack Squadron (VAQ) 130 based at Naval Air Station Whidbey Island, Wash., flew an air pattern over Okanogan County, Wash., on Thursday, Nov. 16, that left a condensed air trail resembling an obscene image to observers on the ground," the US Navy statement to KREM 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," the Navy told Fox News.
"The Navy apologizes to anyone who was offended by this unacceptable action," the statement to Fox News concluded.
The US Federal Aviation Administration told KREM the incident posed no safety risk and that it was not its job to police public morality.
