We developed technology in order to help investigators access archives of documents of the time.

Once of the most interesting things you discover when you read the archives is that lost of things we consider obvious today, was not at the time.

One of those is the usefulness of airplanes at the start of WWI, proven at the end, and the usefulness of tanks at the start of WWII.

The fact tanks were bad weapons at fist, bulky, difficult to operate, slow,low range(compared with big cannons) easy targets, and no ability to cross difficult terrain.

This was improved in an incredible way, for example tank suspension improvements rendered the Maginot Line obsolete when finished.

Lots of people in the army were against change. Making tanks were very expensive, they needed fuel, and they genuinely considered money was better spent on other things.
