The first plane is already ash. You sit outside the school gathering your wits, your breath, your heartbeat to present yourself to your daughter being beckoned right now by her teachers to gather her things and meet you downstairs in the playground.

History will not let you be the calm mother today. As you sit cradling yourself in your arms a second plane enters from the west and plows into the other tower, throwing a piece of landing gear into an alley on Murray Street where your children go to tumbling class in an old artist loft on Wednesday afternoons. The landing gear, never mentioned in news reports of the day, is found years later, confirming your eyewitness.

Your daughter, her first day of middle school punctuated by an unimaginable act, is now in your arms, her red curls tight and coiled as when she left you on the corner of Greenwich Street and Chambers 30 minutes ago. As you escape the school-yard onto the highway your heads turn and look back. Bodies fall like planks from the South Tower. Immediately you wish you could unsee it.

“What would I do? Would I have held hands with a colleague and jumped? Was that the brave thing? Was I brave?” You will perseverate on this every day, even 25 years later.
