Ah ha, a ham eh? Well, I know it _can_ be done Tom, but:
a. Intercom works inside an aircraft, not outside (but this is
legitimate dramatic licence - no actor is going to speak his script
with his mouth covered with an oxygen mask, and all actor pilots feel
that they must be talking to the world, not merely their crew ;-)).
b. You have to use short wave to travel distances like that, and
it does not always work. Whereas UHF or VHF is needed for reliable
short-range r/t.
c. Doolittle says that he will "break radio silence" when it is
all going wrong later to deliver a eulogy to his Raiders over the
radio.
... it's all just so much Hollywood hokum - films shmilms ;-).

... but I must look up more information about the Doolittle Raiders;
that looked like a story to warm the cockles of the heart, even if
the film managed to stretch credibility to the limit (e.g. girlfriend
managing to listen to the intercom or radio from some 4,000 miles
away)!
Well, the ARRL has an award for radio amateurs who communicate with all the
continents ( http://www.arrl.org/awards/wac/ - QRP endorsement) or 100
different countries ( http://www.arrl.org/awards/dxcc/qrp/ ) on 5 watts or
less! So it's not totally impossible, especially flying high at night.
"When conditions permit, I try to work DX with milliwatt power levels. I
have worked 32 countries on 3 continents (NA, SA, EU) with 500 milliwatts
or less. Probably my best QSO was working Aruba with 70 milliwatts." (from
along the Allegheny river - http://www.alltel.net/~johnshan/qrp_ss.html )
