Eisenhower was promoted to the rank of permanent lieutenant colonel

Eisenhower later emphasized that too much had been made of the disagreements with MacArthur and that a positive relationship endured. While in Manila, Mamie suffered a life-threatening stomach ailment but recovered fully. Eisenhower was promoted to the rank of permanent lieutenant colonel in 1936. He also learned to fly, making a solo flight over the Philippines in 1937, and obtained his private pilot's license in 1939 at Fort Lewis. Also around this time, he was offered a post by the Philippine Commonwealth Government, namely by then Philippine President Manuel L. Quezon on recommendations by MacArthur, to become the chief of police of a new capital being planned, now named Quezon City, but he declined the offer.
