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.

It depends on the type of plane. Small, one-engine propeller planes (reciprocating engines) fly at speeds of 80 to 200 mph (130 to 320 km/hr).Jet airliners at cruising altitude average around 500 to 600 mph (800 to 960 km/hr).Military turboprops cruise at 350 mph (560 km/hr) and jet fighters routine exceed the speed of sound (768 mph or 1235 km/hr at sea level).t depends on the type of plane. Small, one-engine propeller planes (reciprocating engines) fly at speeds of 80 to 200 mph (130 to 320 km/hr).
