On Piedmont Flight PI451, a man claiming to be a member of the Black Liberation Army hijacked the aircraft. He demanded to be taken to Cuba and demanded $5 million and the release of his brother’s case in South Africa. The captain advised that insufficient fuel was available to reach Havana, leading to the hijacker locking himself in the lavatory. Upon landing in Havana, Cuban authorities seized the hijacker, who was subsequently sentenced to 15 years imprisonment.On Piedmont Flight PI451, a man claiming to be a member of the Black Liberation Army hijacked the aircraft.
