Greetings, I am 77 and English. I have been into rockets for years and have taken part in National, International and World Championship Space modelling competitions.( Any U.S.A. Team member will remember my spectacular parachute failure in 2008. I didn't pack one!). I was also Team Manager for Great Britain at the World Space modelling championships in 2012, 2014 & 2016. I now dabble with sports rockets up to G class, standing in a field in Wales burning money. At least it's cheaper than playing Golf.
