During an airshow performance, the acft collided with the terrain in a near vertical attitude. The maneuver the plt was to perform was a cuban eight. The first half of the maneuver was flown correctly, however, during the second half of it the acft remained in an inverted position instead of rolling right side up at the top of the loop. There were no mechanical failures or malfunctions reported.
