I like the two-toned name Mach One and the F-4 spiraling across the screen. Could the F-4 be in black and perhaps an italicized lettering to show speed? I mentioned in another post that the letter O in One could actually be a machmeter (speedometer for aircraft) and show the speed at 1 or mach one (the speed of sound). perhaps the O in One could be a mach meter? They typically go from .4 mach to 2.5 mach. I'll post a picture of one on the tournament. It doesn't have to be exactly like it but at least be representative. Thanks.
You know, the more I think about it, at mach one it would be hard to spiral - maybe a tight aileron roll. I like the rendintion where you showed the F-4 flying through the letters which appear to be breaking becaus eof a sonic boom (entry #5). Maybe have the F-4 split the works Mach One?
