33,000 feet? I would assume that the planes have boosters since there is no relay tower between them and the ground towers.

With a decent receiver and antenna I can hear commercial aircraft from taking off at Oakland airport to handing off to Seattle, Denver and LA. In all those cases they are hundreds of miles away by that time. I'm using a broadband discone antenna and a Kenwood TMD700A 70cm/2m transceiver in its extended receive coverage mode.

If you had a scanner programmed to the proper frequency, you could pick up aircraft nearly from horizon to horizon. The radios are not really powerful, but a 33,000 foot high antenna will broadcast a long ways.

If you have the right frequency tuned in, no problem. Normal VHF radios putting out 10 watts will easily cover 25 miles. 33k feet is a tad over 6 miles.

Line of sight communications can travel hundreds of miles. No boosters or relays are needed. 33,000 feet is only around 6 miles; that's nothing as far as distance goes.

Civilian airplanes mostly use VHF frequencies for communications and navigation. Their band is from 108MHz to 136MHz.
108MHz through 117MHz is for navigation transmitters such as VOR's or ILS transmitters.
118MHz through 136MHz is for voice communications.
Strictly speaking, a "police scanner" will not scan aviation frequencies because VHF Police/Fire frequencies are in the 140-ish through 158-ish MHz band.
I own a couple of Bearcat scanners that scan most VHF, UHF, FM/HF and even 800MHz frquencies.
I usually have my scanner going at home and at work and routinely hear cruising airliners talking to Washington Center.

No police scanners cannot pickup airplane transmission. It is not because of distance but rather because the frequecy is not the same...but airport traffic controllers can.

How long is the antenna?
