Czech AH-1Z Viper helicopters return to service in Poland after post-accident grounding

Two Czech AH-1Z Viper combat helicopters returned to service in Poland on Monday, resuming their air-policing mission. The aircraft had been grounded following a UH-1Y Venom helicopter accident in the Czech Republic in July. Notably, the Vipers have still not received clearance to fly in the Czech Republic itself.
