A 6 ft 7 in. friend would like to fly with me to a 1800 ft airport. He is of medium stature and I believe athletic. Does any one have experience or know if it is possible for him to get in and out of a J3 and for me to be able to fly the airplane - I assume he will be in the back seat (cramping the controls). I am only 135 lbs and will be carrying half a tank of fuel. The airport has 70 ft trees at one end and I am anticipating light to no winds. Thanks
