Due to length contraction in special relativity, the length of the field as measured by the observer in the UFO is shorter than 100 m. The contracted length L is given by L = L0 * sqrt(1 - v^2/c^2), where L0 is the proper length (100 m) and v is the speed (0.6c). This calculation results in approximately 80 m.
