On 12 April 2019, a Boeing 717-200 commenced a go around at Strasbourg because the runway ahead was occupied by a departing Bombardier CRJ700 which subsequently, despite co-ordinated TCAS RAs, then came to within 50 feet vertically when only 740 metres apart laterally as the CRJ, whose crew did not see the 717, passed right to left in front of it. The Investigation attributed the conflict primarily to a series of flawed judgements by the TWR controller involved whilst also noting one absent and one inappropriate ATC procedure which respectively may have provided a context for the resultant risk.
