But when Joe reads Abby's prescription bottle it plainly shows the Astoria Memorial Hospital address as 3297 Cedar St. in the city of Astoria, Oregon with the actual Astoria's correct zip code 97103 and area code of 503. The real hospital in Astoria is Columbia Memorial on Exchange St.

The roof is undamaged in subsequent shots (during the filming the airplane actually hit the truck, but this footage was not used in the film).
