Yes Chuck's aircraft was "Glamorous Glen", and he was shot down and interned in Switzerland. Although despite being 'neutral' imprisoned him amongst others. He subsequently escaped with a colleague, and due to the colleagues serious leg injury( Chuck had to amputate it with a pen knife! ) Chuck had to carry his now unconsious friend over the mountains before finally making his way back to the UK, I think with help from resistance members.
Sorry for the somewhat lengthy reply.
