Great Movie - Also check of 'State of Division' AKA Death Race (1973)
Another TV movie aired the same year was "State of Division" starring Doug McClure and Lloyd Bridges. It was produced by Harve Bennet of Star Trek movie fame. WWII pilots with a cripple P40 are chased by a German Tank (actually an American Sherman M4A3)across the desert with a similar duel style ending as in Birds of Prey.
I recommend both of these films for a 'must have' collector.
