On July 16, 2019, the rocket center attempted to launch 5,000 model rockets in an effort to set the record as part of a week-long celebration of the 50th anniversary of the first moon landing. More than a year later, it’s official. Guinness certified that 4,923 rockets fired and reached at least 100 feet in altitude – a requirement for the record. No reason was given why it took a year to announce the record, the paperwork was filed with the numbers a few days after the launch. The previous Guinness World Record of 4,231 model rockets were launched at Teylingen College during a European Space Science Convention in the Netherlands, in the summer of 2018.

An army of volunteers assisted rocket center staff in the rocket launch preparation, with 178 volunteers working 696 hours over 13 sessions to build the rockets. Twenty volunteers worked 75 hours to build the wood frames on which the rockets were placed. see last year’s post http://hararocketry.org/hara/witness-the-spectacle/
