The page basically says,
Never seen before czech gun footage, capturing the actions and shot down of the following pilots, Otty Smika, Miroslava Liškutína, Stanislava Hlučky, Františka Louckého, Otmara Kučery in September 1943, before you could only read about it, but now you can see it with your own eyes but the film quality is really bad. If anyone has any more videos or information he welcomes them. he might have some more videos.
Thats basically what it says, not word for word.
