BYMONEK,
Not quite right on the differences between the -200 and -300 vis a vis tail strike indications (too much time at the beach eh?) though the FCOMS are not really clear on the subject. Both aircraft have a tail strike sensor (that little yellow thingy that looks kind of like another antenna). Scrape that and you will get a TAIL STRIKE EICAS message on either aircraft requiring a depressurization and landing. The -300 also has a tail skid that is designed to protect the fuselage (though technically you have also struck the tail if the skid makes ground contact) and prevent actual damage to the aircraft. Provided you did not completely compress the skid and shear off the sensor, you will not get an EICAS message though you will get a friendly little message from maintenance control who will know about the whole sordid affair through their real time flight telemetry. In this case (no EICAS message on the -300), you should be able to complete the flight as the skid has prevented the fuselage from actually making contact with the runway. You can expect an invitation for tea and biscuits "at your earliest conveinience".
Boeing does make reference to receiving a ground report of a tailstrike with no EICAS message in the -200. There is a remote chance that you can impact the tail without the sensor blade making contact. This requires a pitch attitude in excess of 12.3 degrees with all main gear wheels off of the runway. In this case you are directed to follow the tailstrike checklist (depressurize and land). Suggest taking a look at bulliten EKIB-12.
