Appreciate the responses my questions have generated.
The arguments for cost, I get that, but look where we are at present. Nearly one month since the aircraft went missing and millions of pounds already spent trying to find it.
And, as I write, all we currently have is satellite images of possible debris from the plane.
How much more will it take to recover the parts, look for the black boxes and establish the cause?
Without doubt this and Air France are exceptions to the rule but when it does happen we witness the devastating consequences.
How much per head per passenger per flight to implement the measures and infrastructure? £1? Would most people object do you think?
Personally I wouldn't and if the likes of Apple, YouTube, Google etc. can produce sufficient storage space for the applications, data and media content they hold I'm a solution for holding CVR and flight data can be sourced.
