Border crime causes immense harm to the UK, whether it is the smuggling of people, drugs or firearms, or terrorism related.
There are tens of thousands of light aircraft, helicopters and microlights in the UK, flying in and out of small airfields across the country every day.
Because not every plane and airstrip can be monitored 24 hours a day, the aviation industry, communities who live and work around airports and enthusiasts can play a vital role in preventing crime and maintaining a safe community.
Project Pegasus is an initiative set up to get people who work in aviation or live near airports to join the fight against organised crime and terrorism.
What to look out for:
someone who seems to be testing, studying or researching security around an airfield
buying equipment, chemicals, uniforms or identification like badges or patches
an odd pattern of hiring an aircraft or deviating from an agreed flight plan
aircraft which has been modified, carrying extra fuel, suffering from minor damage, landed short of its destination, has been to remote destinations or isolated airfields or is muddy when only tarmac strips are on the flight plans
the pilot seems nervous, is evasive about passengers, flights or routes, takes unnecessary risks, disregards weather conditions, seems to be flying beyond their abilities or ignores regulations, files misleading or false general aviation reports or flight plans
does it look as if there might be hidden cargo, packages dropped from low-flying aircraft, items being handled suspiciously?
