How were there conversations with people 30,000 feet above ground in an airplane on 09-11-01 when the technology didn't exist until 2004?

Andy-r, The ability to converse via cell phones on planes didn't exist in 2001.

Considering the difficulty in getting a keeping a cell phone connection on the ground in 2001, let alone one at 30,000 ft in a jetliner moving at 500+mph and then having multiple calls go through with little difficulty seems highly improbable. The rapid transitions from one cell tower to another also seem highly improbably considering most cell towers are placed to maximize a coverage area and not to overlap, creating dead zones between areas. It seems like even if a tentative connection could be made, it more than likely would drop the call very quickly at 30,000 ft.

Cell phones have worked in the air from the day one. The limits with any radio wave technology is the horizon. The FCC baned their use because they were afraid that the rapid tower to tower hand off would have adverse effects on the entire cellular system. It turns out it didn't. Today the FAA bans their use however the effect on cockpit instruments is negligible.
Who ever told you this tidbit lied. Take a physics class and find out for yourself.
