As far as I can ascertain the following aircraft were named

TG509 Hector

TG524 Hercules [or maybe Heracles]

WD486 Helios

WD490 Hadrian

WJ328 Horatius

WD500 Hannibal/Hibernia [this was a C4 VIP Hastings ]

There may well have been variations to serials due to the fact that aircraft had to return to the UK periodically for Major Servicing

Can anyone confirm these names/serials
