B25 formation air-to-air (one now Swiss)

I realised that I had some air-to-airs I had taken of B-25s which included the example now registered in Switzerland, but showing it in formatiion with other Mitchells over the US well before it was exported to Europe. Thought it might be of interest. The sound of the Mitchell is very distinctive and to hear three of them at close quarters from the doorless camera ship was something else!
