“Experiments In Spatial Dynamics” “A monstrous arthropod made out of steel with two spindly legs stares vacuously out of its white glassy eyes. Every attempt to name this mechanical being fails, it merely appears as a collision of past and future—science fiction in flesh and blood.”

"For Secret Operation 610, the team built a gigantic robot in an abandoned hangar, its acute angles and sinister forms taking cues from Cold War–era military design.... In the end, the genius of RAAAF is in its strategic interventions that, though small, invite viewers to imagine a completely different way of living." 

— The Architectural Review, 2013

"RAAAF unveiled its Secret Operation 610. This proved to be another meditation on defence, its impact on the landscape and its possible futility against overwhelming odds. Again, it is hard to know quite what to make of this RAAAF project, and yet there is something strangely thrilling in the sight of the most unexpected think-tank studio you will ever have encountered emerging on caterpillar tracks − in the guise of some monstrous Cold War warrior, Captain Condor space vehicle, or giant mechanical crow − from an abandoned F-15 military jet interceptor hangar at Soesterberg airbase."
