I have not found any contemporary news stories to suggest Andrews was a pilot in WWI or was flying before 1919/1920. His name appears in the local Coffeyville KS newspaper from time to time (such as the radio story above). There are some mentions of the fact that he was in the KS National Guard stationed in Coffeyville during 1917 before the unit was federalized and went overseas. He gets promoted from Private to Corporal for example. I believe he went overseas with the unit and saw some action in France.
Here is a story about his unit in France (no mention of him, however):

There are several one or two line "stories" about him in the local newspaper, his visiting a relative, testifying at a trial, even his being sick. I would think if he were flying a plane between 1910 and 1917 there would be a story or two, but I have not found any.
Here is a story from 1917 showing his interest in photography.

Another article from May, 1917 about Andrews seeing Joffre (and Teddy Roosevelt) in Chicago.
