Trouble with a remote controlled plane this size is you have to be able to run fast or have a very long cable  .
It would have been better to use Radio Control. 

There must be hefty insurance costs - if something like that Concorde crashed into the crowd, it could have catastrophic results.

The rules for large models are strict. In the UK the LMA (Large Model Association) deals with airworthiness certification on behalf of the CAA for models over 20kg which are considered under the same rules as full size aircraft.

The pilots are all certified, the aircraft build is monitored from the beginning, the aeroplane has to pass through a programme of test flying, there must be redundancy in the control system (ie no 'single point of failure')
Flights at public events will follow similar rules to full size airshows in terms of separation from the crowd and so forth.
And the insurance comes with the LMA membership, which is nice!

Thank you for an excellent and informative response. As one who until now knew nothing about such things,  most educational!

Cheers! 

You now know pretty much as much as I do!
