[article] A four-seater private aircraft, with only the pilot on board, made an emergency landing on a highway in Madhya Pradesh in rough weather on Tuesday, prompting the Directorate-General of Civil Aviation (DGCA) to launch a probe. The pilot was unharmed. But the spectacle of the small aircraft touching down on the highway in the morning hours startled motorists and brought the traffic to a halt. “The Mumbai unit of the DGCA has started its probe… It has also written to the Baitul district magistrate on the issue,” sources in the DGCA told PTI here on Tuesday night. The district administration was expected to give its response to the communication on Wednesday, the sources said. The small aircraft, said to be Piper PA-30 belonging to NRI Sam Verma, was on a regular sortie when it was caught in strong winds and forced to land on the four-lane highway, about 180 km from Bhopal.
