A small aircraft crashed shortly after take-off from London Southend Airport on Sunday afternoon, killing all four people on board — two pilots and two passengers. The Beech B200 Super King Air, operated by Dutch company Zeusch Aviation, veered left moments after take-off and crashed into a grassy field near the runway, erupting into a massive fireball. Witnesses described the horrific scene, with some saying the pilots waved at children just before the crash. The aircraft was en route to Lelystad in the Netherlands. EasyJet has cancelled all flights at Southend on Monday as investigations begin. Essex Police are expected to give an official statement. Experts suspect possible engine failure.
