The workshops are usually conducted once a month around the KL/PJ area. With the Hot Air Balloon Fiesta being an annual event, there is much need for ground crew to help the many balloonist that come from various parts of the world. To actually fly the balloon, one would need to have a pilot's licence - the balloon is an aircraft.
I've attended their workshops when they first started promoting it about a year or so ago. Nowdays, I just drop by whenever I can to lend support.
I was at Taman Titiwangsa last weekend for one such workshop.
