Protecting airports, airfields and airspace

Project Pegasus is a National Crime Agency, Police and Border Force initiative to increase vigilance along the UK’s aviation environment. 

What is Project Pegasus?

Project Pegasus encourages those who work in, or enjoy, Lincolnshire's airspace to be extra vigilant to counter the threat of terrorism and crime.  It aims to prevent and deter terrorist groups and criminals from operating in and around the county’s airfields and airports. 

It is impossible to say what a criminal or terrorist might look like.  But an individual’s activity or behaviour can become suspicious in the context of the location they are in. 

  • Is the pilot inexperienced, nervous, or vulnerable to pressure? Are they disregarding weather conditions, taking risks with fuel or ignoring aviation regulations? Are they being evasive about passengers, flights, routes?
  • Are there suspicious associates around?
  • Is the aircraft modified to increase range or load, or carrying extra fuel? Is it visiting remote destinations, rarely-used sites and isolated airfields or landing short of its notified destination? Is it regularly suffering minor damage?
  • Have you spotted reconnaissance - attempts to test or research security around an airfield? Have you noticed individuals buying equipment, chemicals, uniforms or badges?  Have you noticed people in the wrong place or odd behaviour? Have you seen any packages being dropped from low-flying planes? Are there signs of disguised continuation flights or deviations from plan? Have you spotted strange or fraudulent patterns of payment?
  • Are all employees appropriately vetted?
  • Is the airfield or site getting extra or unusual use without plausible explanation? Has the site been receiving any puzzling deliveries? Has there been any unusual activity on the ground around a landed aircraft?
  • Are windsocks or lights suddenly appearing? Is activity occurring at odd times, or being disguised or concealed?

If you observe suspicious activity:

  • do not take direct action.
  • do not confront the individual.
  • do not reveal your suspicions.
  • do record as many details as possible.
  • do notify appropriate authorities as soon as possible.

And record the following:

  • who did you observe?
  • what did you see? Be specific.
  • where did you see it?
  • when did you see it?
  • why is it suspicious?


  • Stay Alert
  • Know your environment/workplace
  • Intelligence is everyone’s responsibility
  • Expected the unexpected
  • Suspicious activity; see it, record it, report it!
