I have tracked the second plane! Tail D-BETI. This plane is based in Germany, took off near Wertheim am Main and is flying what seems like a local flight flying NE in Germany towards Northern Germany, possibly up to Denmark. So this second plane is definitely not headed to London. Maybe TS leases the second plane when she does not use it. So if TH is headed to the US, he would probably fly commercial. The internet is scary!
