A 12-day visit to China by a trade delegation from Wichita got off to a somewhat rocky start on Sunday when a scheduled meeting with Hawker Beechcraft suitor Superior Aviation Beijing was cancelled abruptly due to “sensitivity of the ongoing negotiations.” Superior Aviation submitted a bid in July to purchase bankrupt Hawker Beechcraft for $1.79 billion but an exclusivity period for negotiations granted by the court expired on September 1. Since then, there has been no news of progress in those negotiations or whether other bidders have emerged with expiration of the exclusivity period.
