Lockerbie was completely different

If it's a catastrophic structural failure at cruising altitude the cause is immaterial. It could be a SAM, a bomb or a hundred other reasons, but the spread of debris from that height will still be the same.
For PanAm 103, the bomb made a small hole in the fuselage, breaking off the nose cone and an engine. The bulk of the plane continued intact until the plane reached 19,000 feet, at which point it went vertical. The main parts of the fuselage were within 2.4 km.
If this plane was hit mid-section by a SA-11 missile with a 70kg fragmentation high explosive warhead (as claimed), I would imagine glide of any kind would be highly improbable, and debris would therefore be far more concentrated.
