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.
Muscles of the Lower Extremity. The muscles that move the thigh have their origins on some part of the pelvic girdle and their insertions on the femur. The largest muscle mass belongs to the posterior group, the gluteal muscles, which, as a group, adduct the thigh. The iliopsoas, an anterior muscle, flexes the thigh. The muscles in the medial compartment adduct the thigh. The illustration below shows some of the muscles of the lower extremity. Muscles that move the leg are located in the thigh region. The quadriceps femoris muscle group straightens the leg at the knee. The hamstrings are antagonists to the quadriceps femoris muscle group, which are used to flex the leg at the knee. The muscles located in the leg that move the ankle and foot are divided into anterior, posterior, and lateral compartments.
