MH17 down near Donetsk

"If flight MH17 was downed by a SA-11 (...)"

And what could be any other cause ??

The evidence (as seen on pictures of plane parts) shows that a passenger plane flying at high altitude on eastern course was destroyed by detonation of big fragmentation warhead very close to the cockpit area ( distance was few meters at most - the small area of scorched and burned surface and pattern of the shrapnel holes says that).

This could be only SAM or AAM (with fragmentation warhead) and it could not came from the west (the proximity fuse would trigger much earlier then, hitting the rear or center part of the plane).

The fact that missile detonaded passing very close to the cockpit area suggests a nearly head-on intercept course (missle aiming at the target's radar "center-of-mass" - we don't know where it was at this angle aspect, probably somwhere near central part of the plane, but possible radar reflectors are also wing leading edges, whole engines and cockpit with it's windows and front radome). The rest of the plane surface is much less radar-reflective. Missile steers with some possible final miss distance, too. On it's way the missile passes near cockpit and proximity fuse works on.

If we exclude possibility of heavy AAM (with fragmentation warhead) fired by a fighter plane from the eastearn direction, the only other possibility is a SAM with big fragmentation warhead fired from the east too. The Buk system was reported to be in place and shooting other aircrafts, it is said that sattelite data confirms a SAM intercept, not AAM by plane.

Any other weapon (guns) or inside explosion (bomb) doesn't fit to known damage of cockpit area.
