I don't wish to sound patronising but what you're discussing is a serious grown-ups game. If you are part of a team discussing such a project, you shouldn't be asking a question this basic. Take a look, for example, at
http://www.setp.org/ceanderson.html. for an inkling of things that might go wrong.
The pilot needs to be a very experienced TP with fast jet experience, backed up by a very capable Engineering team via a decent telemetry suite. If you are operating in the UK you need B-conditions, if you are operating in the US you need to be working with a big flight test organisation such as NTPS (

Reading your profile, and hoping not to offend the moderator, your organisation already has an unfavourable track record after burning away a large part of dartmoor without proper preparation or even notifying the emergency services of an intended rocket launch. Surely you've learned and got some decent expertise on board since then? Given you've a worse than 50% success rate with unmanned rocket launches, I'd seriously question Starchaser's competence to do anything manned.
