Two of our balloons in Austria passed their annual 100 hours exam in last days. And what's interesting? They have more than 650 (resp. 750) flight hours and both passed grab test exam by Nick Binder, Cameron Balloons dealer with accreditation from the Austrian Ministry of Transport to do C of A on Hot Air Balloons. Both balloons can fly on without any problems another 100 hours.Which better quality test of Kubicek Polyester do you need?

Btw. our first airship AV 1 after 10 years of flying with original envelope made of Kubíček Polyester has 980 hours and more than 1000 flights!!! In this condition it established a new world record in flight duration and it's one of our most successful aerostats.
