Blind Navigation - S5.E4

Academics get stuck in a maze This week the teams have been asked to map uncharted territory. The Hammerlocks, a team of wrestlers from Coventry, and the Academics Anonymous, a team from Kingston University, have to navigate their way around a 'hostile environment' in a vehicle with the windows blacked out.

The Academics seemed to start well but they had a major problem: they couldn't tell when all four wheels of their bus were off the ground or when the bus was level, and this cost them valuable time. They failed to negotiate the first turn in the 'maze', lost their bearings and crashed into the side or the course.

Tension was high as the Hammerlocks took their turn in the 'maze'. They also had problems: their navigational devices weren't reliable. However, they were able to crawl their way around the course using a giant mechanical 'feeler' and eventually made it to within a stone's throw of their target - and into the next round!
