The report on the Socata TB9 accident which occurred at Lambley in March 2016 has been published and it makes interesting reading.
I think it's a miracle that both the pilot and driver of the van came away unscathed.
The AIB have done an excellent job of analysing the performance calculations and there are some valuable lessons we can all learn from this accident.
