Hi
At the time of the picture SEBE was owned by Seibe Public Ltd in it's earlier life it was owned by GAMA as G-CJET. I did my first Learjet annual flight test in this with Ian Cooper taking down all the data etc, very Interesting!!
G-BJDJ started life with Consolidated Contracters
Then to Aravco who changed the Registration to G-RCDI
Then back to G-BJDJ with FJC. It did move to Russia and is now RA-02802.
G-BHLP was originally owned by the AA and then operated by Rogers Aviation before being sold to the US.
