As ever when facilitating my overexpressive hands take over but hopefully I conveyed some decent stuff and I managed to get the group through laying out and simulating a simple rocket design in the brilliant opensource OpenRocket.
There was a lovely bonus for me last night that I got to see this rocket (picture is only half of it!) This rocket was donated to the Manchester Space people and I knew I'd seen the name before... it is Black Streak which has had at least one launch that I know of and its carbon fibre airframe has been up over 20km.... WOW. Very cool to see it in the flesh.
Finally MASSIVE thanks and props to the Madlab team, Claire, Finn, Tim, Sarah and others whose names I've missed.. you made me darn welcome and made everything really easy. Top.
