Corrected entry: The airplane shown taking the young Maria and her husband from Vienna to Cologne is a Douglas DC-3, an American product which would not have been used in Germany at that time. The Fuhrer would not have permitted it! German airlines would have used the trimotor Ju 52.

Correction: This is completely wrong. Lufthansa did operate DC3s during this time.
