Say Cheese, regarding that question of the medical, it may surprise you that your friendly family GP suddenly gets all coy when you ask him/her to sign a statement that you are fit to fly an aeroplane! If you havn't seen your doctor in three or four years, would you really expect him to sign such a blank check without at least checking your blood pressure?
Truly, doesn't hurt to have this box ticked before you spend big bucks on aviation training.
