The Julius Berger expats were travelling in an armoured Merc G escorted by 2 dozen+ soldiers, and look what happened. Bristow is smarter than that: Pack all your staff into a clapped out Toyota Minibus, let them take the same route at the same time every day, a pick up truck with 2 Mopol sporting Nike running shoes and uniforms that are attached with velcro to their area boys outfit underneath, wielding a wip and stick at unsuspecting passers by...the bad guys immediately smell a rat: This surely is a trap of some sort! Probably thought out by security advisers, who are better paid than the pilots/engineers who seem to be happy enough to accept this arrangement without complaining.
