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.

Your jet aircraft usually stay around the same speeds though. Rotate speed is about 130-150 knots (150-170 mph). They then cruise anywhere from 250-400 knots (290-460 mph). Such a big possibility for the speeds because it all depends on the airplane.s fast as necessary to produce enough lift so the aircraft can safely fly. Some can take off with a forward speed of 40 miles per hour, others need speeds that are more than 150 miles per hour, & a few even more than that.
