I watched this last night; never saw it before.
The plot is very hokey, it was done in the early 50's and was obviously little more than propaganda for SAC, but it had some great airplane scenes in it. I've never seen that many B-36's in one spot before - and they were all REAL! Early on in the film a civilian DC-3 declares an emergency and we see it making a single-engine approach to a SAC base, the left engine feathered. After landing, while taxiing to the ramp, the dead engine starts up and the plane intrudes into the B-36 flight line. As it comes to a stop, the door opens and out jump a bunch of 'agressor' soldiers, who are quickly surrounded by Base security. Then a cigar-smoking 4-star (GEN Hawke(s)!!!) emerges to tell all concerned it was just a security check.
Anyway, the photography is outstanding, including a B-47 RATO take-off, an tour through the interior of the B-36 and 9 B-47's in formation. A good view of the last of the piston engine bombers with the first all jet bomber, neither of which ever dropped a bomb in anger. If you get a chance to watch it, it is well worth it.
