20+ years ago a hijacked plane filled with passengers landed at stanstead,about a dozen years back one of the Afghan hijacker’s was found working in Heathrow with an airside pass.
I live exceptionally close to Heathrow airport and know a lot of airport staff,I chatted to a retired immigration officer recently,he told me in his final year working at Heathrow he met TWO asylum seekers he were genuine,only two,he said the system is FUBAR.
