Absolutely Not So!
The H-Bombs are slowed by parachutes so the bomber can get away. The outside temperature for a B-52 at operating altitude over Russia would likely be at least minus 60 degrees F.
Major T, since he was wearing an indoor uniform, would become a solid block of ice before the bomb went off so his TOD has a variance of time between when became a solid chunk of ice and the time of instant defrosting. This could be 30 to 60 seconds. Totally un-acceptable accuracy for even the cadet grade newbe time-nut ;)

He could never have frozen solid in the bomb fall time. I doubt any
material has a sufficiently high thermal diffusivity.
Even if he were dropped into LN2, I doubt he'd freeze more than an inch or
two below the surface.

I didn't say that the bomb had to be falling as you sat on it, but if it is, then, yes, you should wear the proper protective gear. Wouldn't
want the timing to get messed up.

Folks, one doesn't need a thermonuclear device for this sort of almost
instantaneous disintegration.
Standard old high explosives could get your "duration of death" down in
the submillisecond range, and a simple optical pickup could determine
the time when the explosion occurs to nanoseconds (after calibrating for
light time delay).
Black powder which is really a propellant might even be able to
disassemble your corpus in less than a millisecond.
However, if one needs microsecond type uncertainties, then the nuclear
device is probably your best bet. Probably not under a microsecond
though, from simple mechanical disassembly. say you were standing just
outside the approaching fireball... the fireball (in early stages) grows
roughly at the speed of light as the photons proceed out. The question
would be whether there is enough flux to ionize you in a suitably short
time. Basically, you'd have to heat your 100kg or so up to a few
thousand K. Let's see.. 400kJ would heat 100kg up one degree, so 400MJ
would get you to 1000 degrees, which is hot, but not ionized. probably
dead though.
If you were, say, 10 meters away, and your body intercepts 1/2 square
meter of the flux which is assumed spread evenly over 314 square meters,
the instantaneous power of the explosion would have to be 400MJ*628 in 1
microsecond, or about 251GJ/microsecond, or a mere 250E15 Watts
(As I recall, close in, the first thing to come out is high energy gamma
rays, so you'd need to look at the first few microseconds of gamma flux
vs time... I'm sure the data is out there somewhere)

I forgot.. 1 kt (about the smallest practical nuclear device) is about
4.194 TJ. Referring to my handy copy of Glasstone, 99.9% of the energy
is released in about 70 nanoseconds (the last 7 generations), and if
you're reasonably close, then the energy "pulse" hasn't had much time to
spread out, so even a small device is well over the threshold to keep
the variance in your duration of death under a microsecond.

For an air burst, there is a very short pulse of gamma rays coming from the very hot bomb material, until the radiation ionizes & heats the surrounding air. This takes maybe a microsecond. After that the fireball expands as a shock/pressure wave (i.e., well below the speed of light) with enough optical depth to block the gamma rays, so the radiation output actually drops dramatically for a while. This causes the characteristic double light pulse of an air burst.
So, you would want to be close (a few meters at most) to the bomb casing to be sure. Otherwise, you would have to wait for the fireball to get to you, which would take inconveniently long.
Doc Edgarton told a class I was in a story of a bomb set off inside a greenhouse, which he was supposed to take high speed pictures of (through the glass). The prompt gammas immediately made the glass opaque, so all his pictures showed was a blank greenhouse and nothing else (by the time the fireball broke the glass, it was too late to observe whatever he was supposed to observe). The picture looked just like a greenhouse painted white, with no clue as to the fury within.
This is getting far afield, so I will shut up now.

Well, this will all be over in a few days, but while it lasts:
As I recall, the bomber had been hit by attempts to shoot it down,
so it was not at operating altitude. They were all gonna die. That's
why Cowboy rode it down - or maybe the director wanted another
emotional kicker.
Didn't see any parachute, though. Were they concealing stuff from us?
I wonder if electrocuting the brain (with electrodes at the temples)
would be reasonably instantaneous, and considerably less messy. Like
electroshock therapy gone horribly wrong.
One could offer a service - Choose your time of death. Only $1000
for our Kilowatt Eraser. Kill-o-Watt, heh heh.

No..
this is the problem with the electric chair, after all..It's widely
acknowledged to not be an instantaneous death.
People get hit by lightning and survive, for instance.
Unless you physically dissociate the material, you probably can't
guarantee death. It's sort of a timely(!) topic, being close to
Halloween and all... Isn't this the basis for those methods of killing
vampires.. physically separating all the components so that there's no
possibility of reanimation (bringing up the interesting thing that some
of those stories of vampires and zombies probably come from catatonia, etc.)
Remember though, they were flying low to stay under radar and evade the
enemy while going for their secondary target because they couldn't reach the
first. They dropped from a pretty low target, and probably didn't care since
as far as they could tell the world wasn't going to be worth living in if
they got back.
