Due to the entire fleet of 2021 Nova Bus LFS Smart Bus Hybrids currently delivered at the time being taken out of service because of one of the units rear doors opening while the bus was in motion causing all units delivered and units built but not delivered yet to receive new software systems to prevent this issue from happening again. As a result of the LFS Hybrids being pulled OOS, Tuskegee Airmen depot had received 4 Orion VII Old Gen units from Mother Clara Hale depot to cover service on the M31 route while the LFS Hybrids were getting repairs. Manhattanville depot which also had a large handful of LFS Hybrids in their fleet had received several Orion VII Next Gen units from multiple depots across the entire city making their fleet 100% Orion VII NG for a short time period. In this video are clips of Orion VII Old Generation Hybrids #6765, #6776 and #6786 running in service on the M31 route, a very rare occurrence as Tuskegee Airmen once used to have OGs about a decade ago until 2015. All clips taken on October 23, 2021.
