The new missile is about 16 in. longer than the A2, and its bullet-shaped nose is discarded after the missile has cleared the atmosphere, uncovering the warhead (missile engineers call it the rock) which is heavier, more powerful.

The casing, already of glass fiber in the A2, has been improved by a new lining to protect it from the new fuel's greater heat. Instead of nozzles for steering, it uses liquid Freon injected into the side of the gas stream...
University doctors confirmed yesterday that several flu victims admitted to the Health center last week and were suffering from the A2, or "Asian" strain...
Experiments have not yet been completed in Health Center laboratories to determine whether the local influenza germ is the A2 variety, known as "Asian." (It was called "Spanish" near the turn of the century.) When this is done, later in the week, the University will report the situation to the Massachusetts Department of Health...
...have proved to be type B. instead of the Asian mutant of the type A group that caused the last notable epidemic two years ago. Though both virus types cause disease outbreaks in cycles, their peaks occur at different intervals and almost never co incide. Outbreaks of Asian, or A2, flu (which has supplanted the older plain A and A1, or "A prime") run in two-or three-year cycles; they may flare up again later this winter or w?ait until next. Type B flu runs in four-to six-year cycles. The U.S. has had none to speak...
