With COVID-19 vaccines rolling out across the world for the past few weeks, everyone is celebrating in their own way. Some are privately waiting their turn, optimistically hoping this is the start of a return to relative normalcy, while others are taking a more active approach. Samy Kramer, a German pilot, traced a giant syringe in the sky to celebrate the arrival of the COVID-19 vaccines in Europe.

He told Reuters that his goal was not only to create some unique sky art, and celebrate the vaccine’s arrival, but also to get people thinking about getting vaccinated. “There are still relatively many people opposing vaccination,” he said, “and my action may be a reminder for them to think about the topic, to get things moving. Perhaps it was also a bit of a sign of joy, because the aviation industry has been hit pretty hard by the pandemic.”

He flew 124 miles around southern the Lake Constance area of southern Germany to make his point. The syringe outline is visible on the flight tracking website Flightradar24.

Germany began its vaccination campaign on Sunday, December 27, 2020.
