Well, no interest whatsoever? Here's the answer from Tipler's Book:
Argentinian Grand Prix 1977 Warm Up Session
Subsequently, the front-mounted fire extinguisher on Andretti's 78/2, which was behind the oil cooler, exploded right in front of the pits like a bomb going off. It was because it had been filled with the Halon rather than BCF gas, which expanded ar different rates and was overheated by the oil cooler and the sweltering temperatures. It destroyed the front of the car, tearing back the aluminium top skin and blowing the throttle pedal out of the car. The anti-roll bar across the front bulkhead saved Andretti's feet, although he later dicovered that a bone was broken in one foot.
Maybe another one, an easy one? When Honda built the first f1 car, they called it the Honda RA 270. RA stood for Racing Automobile (was asked couple pages before), but what did the numbers stand for?
