False fire alarm in a relatively new tower building.
I wonder why this was not fixed when the tower became operational, or was it a case of someone unnecessarily pulling the lever at a fire alarm station?
It is also interesting to note that many towers in the USA have provisional ops plans in place in the event of such problems.
So, then the question becomes, why do not the folks at LHR have such alternate plans, or if they do, why were they not used?
For example, there was a small fire at the Cairo tower a few years ago, and ATC services proceeded uninterupted, from a van, parked at the airport boundry.
I know, because I was on final for 05R at the time.
So, if the Egyptians can do this, why can't the folks at LHR?
