From the episode 'Discovery'
Here are some photos of the Electric Data Command Centre (EDCC) and cockpit that was built specific for the N9988K known as the mock-up/the stage lady. Both front and back went through various changes throughout the series. Most noticeable was the cockpit, specially in S3. When the mock-up was shipped to Canada, parts were already missing and needed to be replaced, specially the keyboard seen in S1-3.
