Syria | Assad flees to Moscow as rebels capture Damascus

I was under the impression that you can 'frig' the mode C altitude if you pull a particular CB, which causes the system to revert to the aircraft pressure setting for reference? Again, that may be inaccurate.
Not all aircraft installations are the same.

Mode S is required in most airspace anyway and if I remember correctly it usually provides both 1013 referenced and Baro corrected altitude (or just the baro correction that’s been set - can’t remember which). It’s very unlikely that his aircraft wouldn’t have been equipped with a Mode S transponder.

It would not be at all straightforward to frig transponder transmissions.

I definitely know it isn't straightforward. I just seem to vaguely recall something from a course I did over 25 years ago when I was working on B707.

I suspect a 707 would have had a Gilham code connection between the encoder and transponder and cutting one or more of the wires would make it transmit the wrong altitude. These days it’s nearly all serial digital and it’s very unlikely you’d find that sort of installation.

This is why I love this place.

Those 707's were full of Kapton insulated wiring. Absolutely horrible to work on. I think two of three of them are still flying although I believe most if not all of the Kapton has been replaced.

I remember there was a big push to get rid of kapton wiring in the late 80s. Like you say, very difficult to work with.
Tbf this is a bit of a digression from discussing Syria!
 
Just been hearing on the radio that Syria has a tradition of inclusivity so all will be well. Not sure everyone realises the new management are basically ISIS/al Qaeda.
 
A couple of things that don't really make sense with this, all these prisons being opened and everyone being freed, is there nobody in the prison for doing bad things? All just imprisoned by the bad guy because he didn't like them?
And why did asaads lot just give up all of a sudden? Doesn't sound like there was much of a battle for Damascus, sounds like the rebels just drove in and asaads lot just legged it, why didn't the rebels try that before? All seems a little strange
Many of them in the gaols will be from ISIS and from other terrorist organisations.

That’s why Saudi Arabia behead them. No chance of someone coming along and freeing them when they’ve got no nappa.

I suspect most ISIS would have been killed rather than captured. Most in jail are probably people seen as a threat to the former regime for mostly innocuous reasons.
