As your transmission protocol would need to cater for dropouts, multipath/doppler errors etc. you end up with needing double the bandwidth as half of data being sent would be error correction, parity etc.
So unless you are transferring less than 500kB/sec or have a budget of a small county, I recommend packning a 4-bay NAS + power converter on a plane. 10TB can be nowadays kept in a small 4-bay NAS, running four 4TB discs in RAID-5 and happily swallowing 100MB/sec while using 100W of power.
Thus, unless they are doing something really funky on ground and need real-time telemetry there is no point transmitting data. You could theoretically fly 1PB worth of storage even on a Cessna

Never underestimate the bandwidth of a Cessna full of RAID enclosures ....
