Both of these are important in regards to the uncertainty surrounding the Beowulf manuscript, as the works which it draws from or influences suggest time-frames of composition, geographic boundaries from which it could be composed, or range ( both spatial and temporal ) of influence ( i. e. when it was " popular " and where its " popularity " took it ).

The Rankine temperature scale was created to use degree intervals the same size as those of the Fahrenheit scale, such that a temperature difference of one degree Rankine ( 1 R ) is equal to a difference of 1 ° F, except that absolute zero is 0 R – the same way that the Kelvin temperature scale matches the Celsius scale, except that absolute zero is 0 K. The Fahrenheit scale uses ( in the same manner as the later Celsius scale ) the symbol ° to denote a point on the temperature scale and the letter F to indicate the use of the Fahrenheit scale ( e. g. " Gallium melts at 85. 5763 ° F "), as well as to denote a difference between temperatures or an uncertainty in temperature ( e. g. " The output of the heat exchanger experiences an increase of 72 ° F " and " Our standard uncertainty is ± 5 ° F ").

It was under the leadership of LeMay that SAC developed the technical capability, strategic planning, and operational readiness to carry out its strategic mission anywhere in the world.

When LeMay assumed command of SAC, his vision was to create a force of nuclear-armed long-range bombers with the capability to devastate the Soviet Union within a few days of the advent of war.

But the reality when LeMay assumed command was that SAC had only sixty nuclear capable aircraft, none of which had the long-range capabilities he desired.

A key factor enabling the B-47 to become the mainstay of SAC ( and to fulfill LeMay ’ s desire for a long range bomber ) was the development of in-flight refueling.

During LeMay ’ s command, SAC was able to effect great changes in American nuclear strategy.

This was done by LeMay in a 1951 meeting with high level Air Force staff, when he convinced them that unreasonable operational demands were being placed on SAC and, in order to alleviate the issue, SAC should be allowed to approve target selections before they were finalized.

As a result, LeMay was relieved when the Korean War ended in 1953 and he was able to go back to building SAC ’ s arsenal and gaining control over nuclear strategy.

Submitted in a command-wide contest, it was chosen as the winner by a three judge panel: General Curtis E. LeMay, Commander-in-Chief, Strategic Air Command ; General Thomas S. Power, Vice Commander-in-Chief, Strategic Air Command ; and Brigadier General AW Kissner, Chief of Staff, Strategic Air Command.

In 1949 Curtis LeMay was placed in command of the Strategic Air Command and instituted a program to update the bomber fleet to one that was all-jet.

Curtis Emerson LeMay ( November 15, 1906 – October 1, 1990 ) was a general in the United States Air Force and the vice presidential running mate of American Independent Party presidential candidate George Wallace in 1968.

Curtis Emerson LeMay was born in Columbus, Ohio, on November 15, 1906.

His father, Erving LeMay, was at times an ironworker and general handyman, but he never held a job longer than a few months.

LeMay was widely and fondly known among his troops as " Old Iron Pants " throughout his career.

When the U. S. entered World War II in December 1941, LeMay was a major in the United States Army Air Forces ( he had been a 1st lieutenant as recently as 1940 ), and the commander of a newly created B-17 Flying Fortress unit, the 305th Bomb Group.

LeMay was later placed in charge of all strategic air operations against the Japanese home islands.

In January 1945 LeMay was transferred from China to relieve Brig.

LeMay was quite aware of the Japanese opinion of him: he once remarked that had the U. S. lost the war, he fully expected to be tried for war crimes, especially in view of Japanese executions of uniformed American flight crews during the 1942 Doolittle raid.

As a Lieutenant Colonel who served under LeMay, Robert McNamara was in charge of evaluating the effectiveness of American bombing missions.

The order was ostensibly given because of borderline weather conditions in Washington, but according to First Lieutenant Ivan J. Potts who was on board, the order came because LeMay had one fewer general's stars and should not be seen to outperform his superior.

After World War II, LeMay was briefly transferred to The Pentagon as deputy chief of Air Staff for Research & Development.

Though LeMay is sometimes publicly credited with the success of the Berlin Airlift, it was, in fact, instigated by General Lucius D. Clay when General Clay called LeMay about the problem.
