FWIW: I call “B...S...” on the article. It is typical propaganda from the region which overstates the success if any attack. (Remember “Baghdad Bob” claiming the Iraqi forces were driving back the coalition forces as they entered Baghdad?)
To destroy 27 aircraft and kill so many high ranking officers spread around the airfield in a single scud attack, even a massed launch, would be nearly impossible. From a look at Google Earth of the King Khalid Air Base in the Asir region of Saudi, it appears that all aircraft are in hangers (quite possibly hardened)with large distances (with over 100m between buildings)....
Open sources show the Yemeni forces have only the SCUD B, which has a range of @180 miles and an accuracy of 450 meters in range of the programmed target. That is for a properly maintained and expertly aimed missile by a trained crew. — Even if we assume worst case that the Russians snuck in SCUD Ds with longer range and more accuracy and the Russian technicians to fire a massed volley, it would still be a stretch to have such a success.
In reality, we are talking about Islamic fundamentalist irregular forces with the training to neither maintain, nor effectively launch such a weapon system with any accuracy. Yes, they can do effective terrorist bomb attacks, but I think any success beyond getting a single missile into the air in a northerly direction would require extreme or even Divine assistance.....
Optimistic propaganda though.
