Two Lancashire men have denied endangering an aircraft which had to be diverted following an alert.
Tayyab Subhani, 30, and Mohammed Safdar, 41, both of Nelson, appeared at Chelmsford Crown Court.
They were on a Pakistan International Airways flight originally bound for Manchester Airport when the alleged incident took place in May. The aircraft was forced to land at Stansted Airport in Essex.
The pair are expected to face trial in November.
