Tshwaneâs plans for Wonderboom airport dealt blow as all night flights grounded By Rapula Moatshe Share Pretoria - The City of Tshwane's plans of changing the fortunes of the embattled Wonderboom National Airport were this week dealt a serious blow by the SA Civil Aviation Authority's (SACAA) decision to ground all flights scheduled at night due to faulty runaway lighting. This followed an ad hoc inspection conducted on Tuesday by the aviation authority, which discovered that the runway, threshold and end lights were in bad working condition. Aviation spokesperson, Kabelo Ledwaba, said it was also found that the airport was non-compliant with the rescue and fire-fighting requirements.
