Like most Americans September 11, 2001 is burned into ex-pat Dawn Dromgool's memory.
Waking up early in Aspen, Colorado 15 years ago, the now Kaitkati resident said she had a feeling and turned on CNN - something she rarely did.
A man was being interviewed in a tower that overlooked the Twin Towers in New York City, talking as thick black smoke billowed from the tower that had just been hit by a plane.
She watched live as a second plane smashed into the second tower.
"I was just numb in disbelief. They had been saying the first crash was an accident. Now it wasn't an accident."
