A C-87 Liberator Express was reconfigured for use as the first dedicated VIP and presidential transport aircraft and named Guess Where II, but the Secret Service rejected it because of its safety record. A C-54 Skymaster was then converted for presidential use; this aircraft, dubbed the Sacred Cow, carried President Franklin D. Roosevelt to the Yalta Conference in February 1945 and was subsequently used for another two years by President Harry S. Truman.

It appears as small reddish wheals that become visible in response to increased temperature and resulting production of sweat. It can affect all ages. Sweating can trigger intense itching or cholinergic urticaria. The protein MGL_1304 secreted by mycobiota present on the skin such as Malassezia globosa acts as a histamine or antigen. People can be desensitized using their own samples of sweat that have been purified that contains small amounts of the allergen. The allergy is not due to the sweat itself but instead to an allergy-producing protein secreted by bacteria found on the skin.
