DailyMail reports pretty impressive aerial images taking by allied pilots on secret missions during World War II were released this week, you can check it out over here.
The detail is astonishing. At first it looks like just another castle surrounded by tiny houses and neat fields. But zooming in on the courtyard one can see figures milling around.
They are in fact Allied officers being held in the notorious German PoW camp of Colditz and the photograph is one from an archive of aerial photographs taken by airmen - sometimes flying as low as 50ft - during secret reconnaissance missions in World War II.
Until now the pictures have been kept behind closed doors. But they are revealed to the public for the first time today via the internet amid a painstaking cataloguing process.
Pictured below is a site in Peenemunde in Mecklenburg-Vorpommem, Germany where the Nazis build V rockets, as you can see this facility was heavily bombed.
