Talking to media at PIMS after expressing condolences and consoling the relatives of victims of the plane, Shahbaz Sharif said the airline was defaulter of civil aviation authority and due to its poor function, it was stopped from operation. He said it was necessary to find out on whose direction the airline was allowed to resume operations. He questioned as to why a company, which was defaulter of billions of rupees was allowed to play with the lives of women, children and elderly people.  He said there should be investigations into the crash as well as permission to the company. He described the incident a national tragedy and said immediately after the happening, he directed activation of  all the departments of Provincial government and opened Punjab Houses in Rawalpindi and Islamabad for the relatives of the victims. Shahbaz said reports had been appearing in the media that Bhoja airline was a bank defaulter and he had been pointed out that loans written off on political considerations have destroyed the national economy. He questioned how a bank defaulter airline was granted  permission to operate. He said after the tragedy, the Punjab Government extended all the support to the Federal government and Rescue and Elite force teams participated in the relief operations.
