Mr. Kehinde Durojaiye Obasanjo, a wannabe aviator built a locally made engine in a contraption that runs on road and sea. SaharaTV found him operating the contraption in Ikeja to attract minor donors who collect his Compact Disk in which he said he recorded its operation on water.
Mr. Obasanjo said he designed it to operate on three mediums; road sea and air, but has only achieved two which are road and sea. He said he had contacted State Governments including Lagos and Ogun to find support but he only got their promise since beginning of 2013.
