On 22 September 2018, a Saab 340B taking off in accordance with its clearance at Nassau came close to a midair collision over the main runway after a light aircraft began an almost simultaneous takeoff in the opposite direction of the same runway contrary to its received and correctly acknowledged non-conflicting takeoff clearance for a different runway without the TWR controller noticing. The light aircraft passed over the Saab 340 without either aircraft crew seeing the other aircraft. The Investigation noted that the light aircraft pilot had “forgotten his clearance and unconsciously substituted an alternative.
