The pilot showed the police officer that he had 'very limited visibility' from the cockpit when he was on the ground. The pilot explained to the police officer that, '...after he left the taxiway and got onto the tarmac he made a left turn so he could look to his right and the a right turn so he could look to his left. He said the tarmac appeared to be clear of any traffic so he straightened the aircraft and continued to travel east...moving very slow while on the tarmac. After straightening the aircraft...[he] said he heard and felt the crash of the tractor and aircraft...he never saw the tractor or the sweeper.' The passenger said, '...he did not see the tractor.
