The talk will critically review the inroad that WCET research results have made into industrial practice, taking the (aero)space domain as the angle of view, from the vantage point that the speaker has enjoyed for a number of years. The talk will intentionally make a few contentious statements, in addition to those that may slip in inadvertently, in the attempt to stir discussion and to promote some degree of self-critique in the inner circles of the WCETers.
