Don't think you can blame that on Derrick, Dad; the aero kits were a hangover from Randy Bernard's tenure. Anyway, even taxi cabs can get airborne when they get knocked out of their normal attitude and present a big flat underbelly to the airstream.
Robin Miller's article in Racer is a good read; sounds like Derrick is being hamstrung by an Indycar president who won't give him the freedom or budget to do the things he wants to do, much like what happened to Davey Hamilton...
