3X-GCB, 737-200C Adv, 22627/779, Del 11/8/81, Air Guinee Express; Lungi Airport, Sierra Leone:
The Aircraft had just got airborne from Lungi airport in Sierra Leone’s capital Freetown at 14:23 local time bound for Banjul. It crashed into a swamp three miles from the runway, leaving one wing partly submerged in mud. Eyewitness reports say that the left wing caught fire after take-off and that the left engine subsequently exploded shortly before impact.
About 50 pax were treated in hospital for shock and minor injuries but all 126 survived.
You’ll be fine, Ryanair’s machines are perfectly safe. 🙂
