These are NOT REAL. They are (for starters) H1 messages. BAL 767s are
not set up properly for some messages and there are 2 bytes missing in
these. For illustration I will make up a flight number and route to fit
the above above!!

What message 1 really is trying to say is:

BY011AEMA PMI - Britannia flight 011A routing East Midlands - Palma

and message 2:

BY012BTFS LGW - Britannia flight 012B routing Tenerife - Gatwick

as you can see bytes 3 and 4 get "lost" somewhere!!!

This can be verified by "HF" flight numbers appearing around the same
time that fill the 2 digits in.
