Blue Up
After landing the chaps asked the tower that they would like the fire services to inspect the tyres, brakes and engine whilst they held clear of the runway. At this point the fire engines were still in the fire station and probably took 5 min to get to the aircraft. When they did arrive the Capt asked if there was a frequency he could use to talk to the fire services. There was a frequency but tower advised the crew to talk through him as the fire services could only speak Spanish. Later the tower apologised for not having the fire services out earlier as they had not declared an emergency although they had put out a pan call earlier.
As you said Blue Up, a Pan call would only seem to work in the Uk. If you want to be sure of the fire services put out a Mayday.
