The accident report is now out. A thunderstorm was happening at the airport. ATC relayed a wind of 15 knots. Virgin Nigeria said it looked more like 35 knots and therefore delayed the takeoff.
ADC decided to go and hit windshear soon after departure. Their windshear recovery technique of pitching up was excessive and therefore they stalled and crashed. Full noseup trim on impact.
