Mike (The Hand of Fear)

Mike was a member of the blasting crew working in a quarry in England. While they were setting up an explosion, the Doctor's TARDIS materialised in the quarry and the Fourth Doctor and Sarah Jane Smith exited, failing to realise the danger till it was too late. Abbott tried to stop Mike from triggering the explosion, but Mike didn't hear and triggered it. He later helped search the quarry for Sarah Jane. (TV: The Hand of Fear)
