Control by Blow-Off. To hit a distant target accurately, a long-range ballistic missile must be steered in the right direction and must attain the right speed. If it is traveling 23,000 ft. per sec. (15,600 m.p.h.), an error of I ft. per sec. in its top speed will make it miss its target by 500 yds. So when the desired speed has been reached, the thrust must be cut off accurately in a small fraction of a second. This is not too difficult with liquid-fuel rockets, whose thrust can be cut by shutting...
...Melbourne, Australia's Johnny Monckton, a 19-year-old carpenter, bettered the world's record for the 100-meter backstroke by .7 sec. with the time of 1:01.5, later led off the Aussies' 440-yd. medley relay team that thrashed home in 4:19.4 to lower the world's record by .6 sec.

In second place: Pro Joe Weatherly, who brought his Ford Ranchero home less than 2 sec. behind Larson...
...raced the mile in ten months, but Australia's Herb Elliott, 19, grabbed an early lead in a race at Melbourne, sprinted through a spectacular 57.9-sec. last quarter to nip the 4-min. mile at 3:59.9, became the fourth Aussie (after John Landy, Jim Bailey and Mervyn Lincoln) to turn the trick...
