Soon we will find out whether the landing gear was lowered at all on the first approach. That will be key in understanding the rest. Options are:
1. Gear was never selected down on the 1st approach
2. Gear was selected down on the 1st approach but a go around was initiated before touchdown with a premature gear up selection
3 Gear was selected down on the 1st approach but a go around was initiated after touchdown/bounce with a premature gear up selection
