Angel's entire anatomy is naturally adapted to flying. His bones are hollow like a birds, making him weigh far less than usual for a man of his build. His body is virtually devoid of fat and possesses greater proportionate muscle mass than an ordinary human does. His eyes are specially adapted to withstand high-speed winds which would hurt the average human eye. He possesses a special membrane in his respiratory system enabling him to extract oxygen from the air at high velocities or altitudes.
Flight: The Angel's normal cruising speed averages around 70 miles per hour (112 kph), though he is capable of diving swoops that reach up to 180 miles per hour (290 kph). He can fly at 150 miles per hour (240 kph) without the help of a tail wind for up to half an hour at a time before tiring to an appreciable degree. Though he generally flies beneath the height of the clouds ([6,500 feet)(1981 meters)he can reach a height of 10,000 feet (3000 meters)with little effort. With severe strain he can attain the highest recorded altitude of a bird in flight (African geese at 29,000 feet (8840 meters) above sea level), but he could only remain that high for several minutes. - Marvel Wiki
