It is unknown when Bruce built the Batwing or how exactly it was constructed.
Gotham's 200th Anniversary Parade Edit
Batman first used the Batwing to fly out into Downtown Gotham to stop Joker's plan in gassing the crowd with Smilex gas. Batman used the plane to grab Joker's balloons which were filled with the gas and towed them to Gotham Harbor where they flew harmlessly away. He then opened fire at Joker's goons and dropped them.
Shortly after Batman turned his focus on The Joker who goaded him to kill him. He fired everything that the Batwing had but Joker was unharmed. The Clown Prince Of Crime then pulled out a long barreled pistol from his pants and fired a direct hit at the Batwing causing it to be critically damaged and crashed into the steps of the Gotham Cathedral.
Behind the ScenesEdit
The construction and filming of the Batwing model was overseen by Derek Meddings.
A full scale cockpit was built to film with Michael Keaton inside. The cockpit was rocked in front of blue screen to achieve the desired effect. B-roll footage of the filming of these shots can be seen in the vintage Making of a Hero documentary.
