the only thing i can say is the con air dvd zone 1 is 111 min and the crimson tide dvd zone 1 is 115 minutes.
does it mean Con air is the extended edition and not crimson tide ?
Just look if there is "allemand" on the case. That means german in french.
To check if Con Air is the Extendend Cut you could take a look at this and check if the extended scenes are in it. There are some longer scenes you could check for, for example where Cameron speaks to the female guard.
