...before lights took over.
Just watched the Brunswick films footage of the 1973 season and the US GP was flagged off with a green flag. That's obviously normal for American racing, but obvioulsy everywhere else got under way under the national flag.
Was that a normal thing for the US GP? Or an anomaly for that year? Or maybe is there some flag etiquette that prevented the Stars & Stripes being used for something so comparatively frivolous as starting a race?
(Some great asides in the film incidentally - Beuttler's team telling him to stop practising as they'd already got 30 laps on their only set of tyres, someone at Firestone offering a disbelieving Hunt a new set for testing...and some sad ones as well...)
For that matter, I don't think any U.S. races are started with the national flag. Reading the Flag Code, 4 U.S.C. Sec. 1, et. al., there are several provisions that might be read so as to preclude, or at least make difficult, the use of the national flag to start a race:
· The flag should never be dipped to any person or thing, unless it is the ensign responding to a salute from a ship of a foreign nation.
· The flag should never be displayed with the union (the starred blue union in the Canton) down, except as a signal of dire distress in instances of extreme danger to life or property.
· The flag should never be drawn back or bunched up in any way.
· The flag should never be used for any advertising purpose
· The flag should never be fastened, displayed, used, or stored in such a manner as to permit it to be easily torn, soiled, or damaged in any way.
· The flag should never be stepped on.
· When the flag is lowered, no part of it should touch the ground or any other object; it should be received by waiting hands and arms.
