Again if you look at the aerial photos there's no marks on the runway to indicate heavy braking etc.. Landing long, engines spooled down, flaps land, initial heavy braking then attempting a go-around/balked landing, be very easy to pitch up too quickly, engines not spooled , flaps in transition and stall..made even more aggressive by the short runway, car park etc in front...
If the 150kts vref is correct then flaring, ground effect are going to make that thing float!
