Hero Dog
Can anyone tell me what is the error in the following story?
"Near Grandpa's farm the railroad tracks made a hairpin turn between two stony cliffs. From his fields, Grandpa could see the tracks. If rocks fell upon them , Grandpa climbed the the hill and warned the engineer by waving a red flag.
One day Grandpa saw rocks falling on the tracks. He started for the hill as a train approached, but tripped and knocked himself unconscious. That's when his dog proved his mettle.
The dog raced to the house. He quickly pulled down Grandpa's long red underwear from the clothesline, raced to the hill, and there ran back and forth, trailing the red underwear like a warning flag.
The engineer saw the red signal and stopped the train, saving hundreds of passengers from death or injury.
The dog was later given a medal due to his act which saved lives of hundreds of passengers."
So whats the flaw in the above story?
