buses, we accepted them by the end of dec. To enable nabi to get paid. Through the month of jan, we continued to fine tune the buses. Finally, we started road testing them on feb. 19. On march 21, one of the buses caught fire and nearly burned to the ground. After disabling the component thought to be the culprit, we continued to road test the buses. In april, we had another bus catch fire in a different area of the bus. Again, all buses have been deadlined.
