First generation 737s (-1xx/-2xx) had a built in stairs under the 1L door. We (United) have removed it on ours and I suspect other airlines have too. Why? I don't know officially but I suspect the weight penalty - there are very few airports where you would use them today. I don't know if it's available on 2nd gerneration 737s. -- Larry Stone | United Airlines VAX and HP-UX Systems Administrator | Maintenance Operations Center email@example.com | San Francisco, CA 415-634-4725 All opinions are mine, not United's.
