I watched a vid on the BBC website today and it appeared to be an SA-3 SAM. At the start of the vid, the missile shown was definitely a 2 stage one with fins near the front too. THe SHAHABs appear to be be 'scud-like' with a single set of tailfins.
I wonder if the sabre rattling will lead to anything though!
Watching the night firing vid on BBC, shortly after take-off their rockets seem to spit out all sorts of glowing particulates - ie stuff that continues burning outside the engine. What's that about? Disintegrating boosters, crappy engines, IR Chaff for the early boost phase or what? Or are these just great big cardboard fireworks designed to go up and trail a good pyro flare to look nasty? We've never seen any vid of downrange now...
As for a stuffed up launch, I heard a tale once about one of the first demos of Lance on a UK range. Unfortunately in his excitement to show off the new toy, someone forgot to untie the restraining webbing, so the whole unmanned TEL jumped pretty high before making a big mess.
