A statement from Southwest Airlines read:'Following an uneventful landing, local authorities met the aircraft at a gate and removed the disruptive passenger.

'The safe operation of every flight is our highest priority and we expect the aircraft to depart shortly to complete the journey to Houston.'

Video taken by passenger Kristy Gillentine showed the woman being wheeled off the flight by police.

In another video she took, a fellow passenger told her that the woman was up against a wall in the airport terminal yelling at passersby about how 'the government was unfair to her and her family' and that they 'experimented on her and forced her to walk backwards'.

Gillentine later tweeted she was very concerned that the woman was allowed to board the flight.

In response to her tweet, Southwest tweeted that the airline was working to comply with directives.

Passengers who witnessed the incident were held aside for questioning, while others waited in the airport ate Domino's pizza provided by the pilot.

The FBI is currently investigating the incident, according to Corpus Christi International Airport.
