The two Cape Canaveral Launch Complex was built to launch Thor missiles in the 50s. The two pads ended up as the launch site for dozens of Delta rockets over the past many decades. Now the complex’s historic launch towers have been demolished to make space for something new. These towers helped to launch several high-profile NASA missions over the years.

Since then, these two launch towers were unused for more than a decade. Watch the video below:
