− | '''SSI-86''' (project designation '''CY-2'''; also called ''BalBal'') was the second launch of [[Cycloon|Project Cycloon]] on May 18, 2019. It featured a legacy ballast mechanism from ValBal operated by Cycloon avionics and thus marked the beginning of ''#cy-flops'', or ''Cycloon flight operations''. The mission was noted for its low-altitude profile, unexpected interaction with inclement weather, and most remarkably, resumption of flight a full 24 hours after presumed flight termination, the only such occurrence in SSI history. | + | '''SSI-86''' (project designation '''CY-2'''; also called ''BalBal'') was the second launch of [[Cycloon|Project Cycloon]] on May 18, 2019.
