A bronze plaque created by Czech sculptor Miroslav Zvonek is housed in the Kent Battle of Britain Museum and pays tribute to the four Czechoslovak RAF pilots Josef František, Josef Balejka, Matěj Pavlovič and Wilhelm Kosarz. They met in Poland after the occupation of Czechoslovakia, and even in the United Kingdom they flew Polish squadrons. With 17 kills, Josef František was the most successful non-British allied pilot of the Battle of Britain and one of the best flying aces of the entire Second World War. A delegation from the village of Otaslavice, the birthplace of Josef František, and the Ambassador of the Czech Republic to the United Kingdom, along with the Deputy Slovak Ambassador, came to unveil the plaque.

"The commemorative plaque is composed of four parts dedicated to individual pilots. The whole project even more interesting by the fact that copies of individual parts will be subsequently placed in the home villages and cities of these heroes. The time in which this memorial comes, the time of Russian aggression in Ukraine, underlines the importance and the legacy it carries", commented Ambassador Marie Chatardová on the unveiling of the memorial plaque.

On this occasion, representatives of the Embassies of the Czech and Slovak Republic also visited the Battle of Britain Memorial in nearby Capel-le-Ferne, where they laid a wreath to honor the memory of 88 Czechoslovak airmen who took part in the battle.
