When we call the emergency services for any incident, we have a system to notify them of the seating capacity of the particular aircraft involved, this allows them to assess how many personnel and what equipment should be sent to the incident.
I know that this system exists at many other airfields throughout the UK, and it's proven to work well and be a very efficient system.
As for the flippant
remarks from a few amateurs inferring overkill by the emergency services, it's not just you that the emergency services are concerned about.
If you're making a forced landing, the services have to assume the worst, for example, that any resultant fire or impact from your predicament may have detrimental effects upon other people or their property.
It doesn't really matter how many of the emergency services turn up, because they can always turn back, start to worry when they don't show at all.
