Huge bang erupted on United flight that began plunging out of the sky during turbulence so severe four flight attendants were injured

Severe turbulence on a United flight injured four flight attendants on Wednesday night. 

Passengers said the turbulence felt like a sudden drop after hearing a 'huge bang,' with one witness reporting that one of the injured flight attendants had blood on their head and leg.

Four flight attendants total were seen by medical personnel, including one being transported to the hospital for further treatment, United told The Daily Mail in a statement. 

Two flight attendants, aged 58 and 62, sustained neck and back injuries, according to a radio call recording obtained by ABC 7. 

No passengers were injured, the United statement read.  

United Airlines Flight 1157 left Honolulu, Hawaii and landed in Los Angeles, California safely, ABC 7 reported. 

Emergency medical services were dispatched to the gate at LAX when the plane arrived.

'It only lasted a couple of seconds, it felt like wake turbulence, but we're smooth now,' a pilot said to air traffic control, according to the outlet. 

'I was watching a movie and all of a sudden we just drop,' passenger Marly Wadlington told ABC 7, 'and it felt like we dropped pretty far.

'It started shaking, everyone was yelling. We were all super scared.'

'There was a huge bang and then we started falling,' Coral Pena said in a live interview with ABC 7 shortly after the plane landed. 

After landing, the plane waited on the tarmac for around half an hour while a gate became available, one passenger told the outlet.  

The aircraft was a Boeing 777-200 twin jet. Aboard were 190 passengers and 10 crew members. 

The Daily Mail has contacted United and the relevant airports for further information.
