Basic, basic flying on approach/landing is - aimpoint, airspeed.
That's really BASIC flying. It didn't happen.
Watching guys eyes on final below 1000'. Longest interval to glance to at airspeed is typically 5 seconds. It can be as quick as every two seconds. At 500' they were was slow and correction took over 40 seconds, and perhaps 50 seconds? What were they looking at?
NASA has done eye tracking studies. They probably have the data on how often crews look at airspeed on final.
