Wheeltug - the novel answer to marginal airline profitability

WheelTug Update

How is WheelTug doing with their development program? The story, link below, is around six month’s old, and it states: “Delta Airlines will get the first WheelTug-equipped 737s by late 2009, and at least one automaker is talking with Chorus as we go to press.”

I am curious if this installation is a new 737 delivery involving Boeing installing the WheelTug, or a retrofit to an existing Delta 737. It reads like certification will be done by then too. If so, has there been an installation done yet using production parts? Rahosi, are you still monitoring this forum? If so, can you bring us upd to date?
