Coming in to land the plane suddenly just dropped like a stone. Felt like it dropped a long way, Lots of screaming. Then it shook and bounced around. Captain announced there was a, weather system he would have to go around. Absolute slince as we edged past huge columns of cloud then a very bumpy landing. Ended up in a part of Alicante airport I haven't been to, about 2metres below all the other planes. Got on a Jetway after 35 mins , no passport control.
