You will be asked by the air base doctor to complete a questionnaire, answering general questions about your medical history. Doctors are concerned with any existing condition that may be aggravated by the stress of a flight. Potential problems include excessively high blood pressure, heart trouble, kidney stones and gallstones. Your blood pressure will be checked and you may be asked to ride an exercise bike, etc. We advise you to check with your personal doctor before leaving for Moscow should you have any health concerns.
