Wake Turbulence?
IF IF IF
this was wake turbulence.
We had a nasty at RAE Bedford in the 70s when a Hawk was close behind a large transport (Britannia).
It seemed the worst situation is a large mismatch between leading/following aircraft sizes? and a crosswind of about five knots. Instead of spreading outwards at about five knots as usual the upwind vortex is held at or about the runway giving a large rolling moment near the ground.
It may be the changed control laws of the Airbus near the ground complicate the handling in this situation
All said with the aim of spreading the word not stating what happened
