25 June 1937: Leg 25. After flying from Bandoeng to Soerabaya the previous day, a problem with Amelia Earhart’s Lockheed Electra 10E Special, NR16020, could not be repaired there, forcing her to return to Bandoeng.
“In the air, and afterward, we found that our mechanical troubles had not been cured. Certain further adjustments of faulty long-distance flying instruments were necessary, and so I had to do one of the most difficult things I had ever done in aviation. Instead of keeping on I turned back the next day to Bandoeng. With good weather ahead, the Electra herself working perfectly, the pilot and navigator eager to go, it was especially hard to have to be “sensible.” However, lack of essential instruments in working order would increase unduly the hazards ahead. At Bandoeng were the admirable Dutch technicians and equipment, and wisdom directed we should return for their friendly succor. So again we imposed ourselves upon these good people to whom I shall be grateful always for their generosity and fine spirit. A particular niche in my memory is occupied by Colonel L.H.V. Oyen, Commander of the Air Force, H.A. Vreeburg, chief engineer, and so many K.N.I.L.M. personnel to whom I would like again to say ‘Thank you’.”
24 June 1937: Leg 24a, 24b. After three days of maintenance and repair work on her Lockheed Electra at Bandoeng, Java, Dutch East Indies, Amelia Earhart started warming up her engines at 3:45 a.m. in preparation for a long transoceanic flight to Darwin, Australia.
However, problems with an instrument delayed the takeoff until 2:00 p.m., making Darwin much too far away. They didn’t want to arrive there during hours of darkness. If Fred Noonan’s navigation was slightly off after a long over water flight during darkness, they might not find the small airport.
Instead, they made a short hop to Batavia (now known as Jakarta) and from there, continued on to Soerabaya for a total distance for the day of 355 miles (571.3 kilometers).
“After that late start we reached Soerabaya when the descending sun marked declining day. In the air, and afterward, we found that our mechanical troubles had not been cured. Certain further adjustments of faulty long-distance flying instruments were necessary, and so I had to do one of the most difficult things I had ever done in aviation. Instead of keeping on I turned back the next day to Bandoeng.“
