RAF Hawker Hurricane Mk IID or IV probably belonging to Specialised Low Attack Instructors School, Milfields, Northumberland. It's armed with Vickers anti-tank guns, this particular airplane being equipped with the standard carburetor air intake.
The Polikarpov I-16 is a solid little machine. You only have to be involved in pushing it around to know that it feels like it’s made of bricks. When outnumbered and out of ammunition, Soviet pilots on the Eastern Front resorted to ramming German bombers. In the least dangerous method (still more than scary) a Soviet pilot would hit an enemy plane with a part of his own, bumping it with his wing for example.
