Emergency Vehicles Are Responding: Listen to Air-Traffic Controllers React to S.F. Crash Landing
on the tapes I could hear the controller notify Asiana 214 that emergency crews were responding. The pilot must have communicated some sort of problem to the tower. It is at around 1:52 on the following link

Hearing from a regional airline buddy who was deadheading through SFO when this happened that TSA and Customs were creating real problems for rescuers.
TSA not allowing rescue vehicles on the property till inspected, and Customs not letting the injured leave until they cleared them.
Anybody able to confirm this??
