These will be the people I am looking out for at the 9/11 Memorial:

I’d like to set this up by mentioning how many stories we hear about people who were suffering in the building and miraculous escapes. There are hardly any accounts from those on board the dreaded flight 11, 175, 77, and 93. The 9/11 issue of New York Magazine tells the courageous account of Betty Ong.

Here is the audio of her phone call.
