Signs of Lyme disease include skin rash and painful inflammation of joints (particularly the knees), accompanied by flu-like symptoms. The symptoms of Lyme disease increase in severity as the disease spreads though the body. Early diagnosis and treatment are important to stop the progression of the disease. If untreated, the disease can result in neurological disorders such as peripheral neuropathy, including Bellâs palsy, as well as pain, numbness or weakness in the limbs.

The unofficial record speed is also inconsistent with data from the National Museum of the United States Air Force, which gives a top speed of 520 mph (840 km/h) (Mach 0.70), nonetheless, making the XF-84H the fastest single-engine propeller-driven aircraft until 1989 when Rare Bear, a highly modified Grumman F8F Bearcat reached 528 mph (850 km/h) (Mach 0.71).
