Although ""Hail and Qaseem"" bring back some difficult memories for those who still remember, it is said that time passes and heals all wounds - or that people tend to forget lessons learned. The records show that Westinghouse decided to take two more orders for crude-oil fueled plants (Asir and Jizan) in the mid-1990s. Presumably, enough was learned about fuel pre-treatment, as well as negotiating contract terms, over the 10 or more years since the signing of the Hail and Qaseem contracts. (It is believed that all of the crude-burning plants in Saudi have since been converted to natural gas fuel, and some to combined cycle operation.)
