If they evade detection at both ends of their journey, how does anyone know to add them to any statistics ???
If there are scanners that can detect stowaways on trucks entering the UK at the docks, can't there be a similar hand-held device with which aircraft wheel wells can be checked? Bit of an over-kill (sorry) as it cannot happen very often and I dare say not many can attempt this activity at one go.
