A stand at the Airshow?
No. We had one years ago. It costs about 25 grand and on a return for investment basis it is not worth it. We do sell something, membership. The people who attend airshows tend to be aircraft enthusiasts, not Engineers.
We would prefer to send a team to Vegas each year to showcase what we can do in the global Aircraft Engineers competition. When over there we share experiences with our counterparts and we always rank high in the final standings. Btw I have never attended the comp, it is for our members.
