77 years ago, 1 of the 18 AT16 prototypes were selected for a limited production. Tortoise would be the 2nd heaviest machine ever constructed in the UK (TOG was 1st). Its use to test the weight limits of bridges was crucial to future tank design and logistic planning. http://pbs.twimg.com/media/EuGtnACXcAQzvSw.jpg
