Emergency landing is a possibility
True, but the flight time from DFW to AUS is about 30 minutes. You take off and while climbing to Cruise Altitude for about 5 mins there and then start lining up for landing as the Cabin Crew is doing a high speed Beverage Service cleanup and stowing the Service Cart.
As far as E-Landing sites they would be Waco or Killeen/Ft. Hood as far as I know.
The loose screws (besides Me) were 4 or 5 in a panel with 25 plus total screws. It was a 737 so FOD wasn’t a concern in My head. I was more concerned with the rest of the Pax freaking out about it.
