Hey Falconeer! Welcome to the Ooniverse...
Glad you're enjoying 'Status Quo', don't forget there is a sequel too - 'Mutabilis' if you need to find out a little more about Rebecca and a few other oolite short stories available via
my website.
As for a picture, I modelled Rebecca on 'Bechs' played by Hilary Swank in 'The Core'.
That could easily be the cockpit of a Mk3 Cobra...
There is also a great piece of artwork on the elite wiki page for mutabilis near the bottom which gives a fan's view of what Rebecca looks like. (Can't access the wiki at work, can anyone else link to the unsuccessful mutabilis coverpage entries?)
Daddyhoggy is also correct in mentioning that there is a 'Rebecca' on the forum, a triggerhappy young lass if I recall correctly, but she's not my 'Rebecca'... if that makes sense.
You can also meet Rebecca inside the game if you install my Tianve Pulsar OXP, fly to the Tianve system (Galaxy 1) and visit the Pulsar. Rebecca will provide you with an appropriate warm greeting as befits her personality...
Cheers,
Drew.
