Based on the true story, l think it is a great movie but l like it.When l am watching the movie on 30 September 2019.I know this movie are follow the true story to make it.And then,l have see when the pilot have be ready for boarding before,then they will use an i-pad to check the critical point,how long does the oxygen lastly and the weather report.Other that,all airline's cockpit also will have the pilot flying and the pilot monitoring since they also need to follow the standard operating procedure to do the job.The pilot monitoring should went to outside to check the landing gear,airline's engine 1 and 2 and everything else.As well as,the passenger can be start for boarding right now.
