Just to confirm with everyone, I was able to complete 7 1/2 hours from EGLL-KEWR yesterday using UT minus the HL*.bgl files, LDS, ASV, FS2Crew, UK2000 EGLL and Simflyers KEWR. No errors no issues. Please go read the UT thread on the simforums to keep abreast. This could turn out to be a tremendous fix for the community....-Paulhttp://www.simforums.com/forums/forum_posts.asp?TID=19466

Thanks, this is very interesting. I have viewed UTUSA with suspicion in the past regarding OOM errors, but it is such a critical addon to my flying experience that removing it is a non-starter.If I remove the HL*.bgl files, does this mean I lose the high detail coastlines?
