It is thought that the coup was planned for few or several weeks later. They learn that the prosecuter is close to the end. Coup members immediatly come to their work, leaving their holiday or annual leaves. They start to prepare for the coup. At 15:00 or 16:00 central inntelligence learns that something is going on due to a leaker. At 18:00 military meeting and intelligance agree to close the airspace. At 21:00 or 22:00 coup starts beacause they are known. The actual plan was for 3:00 or 4:00 in the morning. And you know the rest, FaceTime, insider (pro-government) military members, starting too early due to a leak etc made it uncessfull coup.

The coup members execute the constitional military idioligy/law of the Turkish military, that is to prevent both ousider and insider enemies. Here insiders are islamic nuts. Take control, establish Ataturk's 6 (iirc) main points; united republic, secularism, Turkish state, etc. Then they leave. Thece principle are almost same as modern western priciples in ethnic countries like Spain or France, but not like Switzerland or UK.

Sadly Turkey is not only geographically between Europe and Middle East but also idiologically. Ataturk was from Europe. AKP supporters are from eastern parts of the country.
