I want to express my great regret by telling you I had to delete the 
whole Shannon-Limerick Airport right at the last moment. The problem 
was this:
when I was taking off from runway 6 with any Jet-Aircraft, a part of 
the scenery was also "taking-off" with me (Note: I use SGA running 
at 800 by 600 with ATI Vga Wonder Driver), with relative machine 
hang-up. The problem disappeared when I changed resolution to 
standard VGA mode or when I started it together with US Default 
scenery. After three days of intensive debugging I realised there was 
no workaronud. I tried everything: debug, decoding, assembling and 
disassembling. I changed so many bytes: nothing to do. I had to 
give-up. Such a fine airport! Its 6/24 runway was 3200 mts. long 
right away, good for 747 also. I left the Shannon VOR, 113.30. Hope 
you will find it useful. I included the original Shannon area, in the 
hope someone more patient and clever than me will debug it.
The file is SHANDEBG.SC1.
The area has no SEE ehnancements. I give you an advice I hope you 
might find useful: I think the bug should be about the RAMDAC and the 
Graphics Controller, so investigate them.
Another BUG was in CORKSCEN.SC1. The machine halted when the scenery 
just loaded: there was a little corruption in the header, and I 
successfully fixed it.
If you cannot find any solution about Shannon, let me know: I will 
try to re-design it (Sigh!).
