Then there are outright broken sentences like this:

>The 1980s saw an increase in threats capable to countering the SR-71, including improved enemy air defenses and the introduction of the MiG-31, which was armed with the R-33 air-to-air missile could intercept the Blackbird.

This just breaks my mental parsing, since there are so many ways to fix this:

1. ..MiG, which, being armed with the R-33 missile, could intercept the Blackbird;

2. ..MiG, which was armed with the R-33 missile, and could intercept the Blackbird;

3. ..MiG, which was armed with the R-33 air-to-air missile, and therefore could intercept the Blackbird.

(and so on)
