The balloon field was crowded Saturday evening, as the competition flights began to take off for the 2019 National Balloon Classic. Sunday flights were cancelled due to rain. Today is Pilot Appreciation Day at the National Balloon Classic. Competition and mass ascension balloon flights begin at 6:30pm, with Trainwreck providing the headline entertainment. The KNIA Lil’ Big Red Radio will be on location on the balloon field, playing music and giving live updates.
