The Obama campaign had chartered the MD-81 from Midwest while its current campaign plane, a Boeing 757 chartered from North American Airlines, was being reconfigured. It was put into use on July 20.
The McCain campaign also debuted a new plane last month, a Boeing 737-400, chartered from Team Jet. A spokesperson, Brian Rogers, said he was unaware if the incident with the Obama plane had led to any safety evaluations of Senator McCain's campaign plane.
