Here is another set of model aviation-themed comics, this time from the November 1953 issue of Air Trails magazine. Interestingly, the middle comics mentions an "X-115" experimental airplane that claims to be able to hit 850 miles per hour. It seems to be an obvious allusion to the North American X-15 airplane, which on its first light on June 8, 1959 was flown by Scott Crossfield to a speed 840 kilometer per hour. Mach 0.79 = 522 mi/hr, Mach 1 = 1,235 km/hr = 767 mi/hr. The two numbers are amazing close, although the units are different. There is a list at the bottom of the page with links to all the model aviation-themed comics I have scanned and posted so far. Enjoy!
