According to WGN, Chicago Fire received a call about a plane on Lake Michigan. There was no telling what crews would find once they arrived near Navy Pier where the plane was spotted. Thankfully, the first responders would need any rescue apparatuses for this call.

As you will see in these photos shared on Chicago Fire Department's Twitter, everything was OK. In fact, WGN shared the story on Facebook saying those inside the plan just wanted to go for a quick swim. Imagine that?
