IAC is pleased to announce that we have expanded our archive of aerobatic sequences to include Unknown and Free programs as well as the Knowns. Visit: https://www.iac.org/sequences (member login required). Or you can find it under the Pubs/Archives menu item.
If you would like to contribute Freestyles -- your own or paperwork saved from contests -- please email them to webmaster@iac.org and I'll post them. PDFs are preferred, but GIFs and JPGs are OK too.
Many thanks to Brian Howard, who provided a treasure trove of nearly 800 (!) Unknowns dating the year 2000 through 2013. That is a serious amount of practice material!
