I hate to disappoint the conspiracy artists among yourselves but the Facual NTSB Report states :
On July 27, 2010, at 1139 local time, a Boeing MD-11 equipped with General Electric CF6-80C2
engines, German registration D-ALCQ, operated by Lufthansa Air Cargo as flight 8460, reportedly
caught fire after a hard landing at the King Khalid International Airport, Riyadh, Saudi Arabia.
The flight was a scheduled cargo flight from Sharjah, United Arab Emirates (UAE) to Riyadh, Saudi
Arabia. The two pilots were transported to the hospital with injuries, and the airplane was
substantially damaged.
The NTSB has no interest in this other than to establish cause. It will then usually make some safety recommendation or another.
If it were really so that the Saudi's had something to hide, my guess is that this thread wouldn't be here....
