Dave Rowberry was an RAF Lightning Maintenance Crewman.He is a very nice man and developed many small gliders and aircraft for flightsim as freeware,however some flightsim community members were so abusive to him that he gave the whole thing up.
I very much doubt you will be able to contact him.The aerosoft venture was his last.A real shame.
Cheers Chris
