An RAF spokesperson said student pilots are conducting a training exercise in the helicopters.

An RAF spokesperson said: “RAF Chinook helicopters from 28 Squadron based at RAF Benson in Oxfordshire are conducting operational flying training at and around RAF Woodvale, near Formby in Merseyside.”

This exercise is the operational flying phase of the Chinook Operational Conversion Unit (OCU) where student pilots are prepared for operational flying before they join the Chinook Force at RAF Odiham in Hampshire. 

The exercise started on the 11th of July and is scheduled to finish on the 22nd of July. 

According to the RAF website, the Chinook is an “extremely capable” and “highly versatile” support helicopter that can be operated from land bases or ships.

It may be armed and is fitted with self-defence equipment.

The aircraft is primarily used for trooping, resupply and battlefield casualty evacuation.
