As I recall, earlier versions of the 737 cruised at a relatively slow .74M (485mph), while later versions have increased to around .78M (510mph). Maximum speed is ,82M, or 51 â¦ 1 mph.     If you have flight simulator 2004 or Flight Sim X the top speed is 340 kph.s I recall, earlier versions of the 737 cruised at a relatively slow .74M (485mph), while later versions have increased to around .78M (510mph).

Some of the major muscles of the calf include: 1  Gastrocnemius (calf muscle): One of the large muscles of the leg, it connects to the heel. It flexes and extends the foot, ankle, and knee.  Soleus: This muscle extends from the back of the knee to the heel.
Biceps femoris Muscle & Hamstring Muscles. The biceps femoris muscle is one of three hamstring muscles that run down the thigh. It enables the leg to rotate and move in the ways that it does. The short head controls movement and flexibility around the knee, or knee flexion and the long head controls hip extension. Injury to the biceps femoris, or any of the other two hamstring muscles is collectively referred to as injury to the hamstring.
