A few posts ago we were discussing the carriage of four legged SLF in the 'K'.
On the Sri Lankan Air Force website there is a video of two elephants (in crates !) being loaded on a Sri Lankan Herc. They were on their way to Prague Zoo. Sri Lanka has two a/c I believe both ex RAF 'K' models but which serial numbers I know not. Cue Coffman and his forensic skills.
There is a suggestion that they backloaded some equally exotic animals back to Sri Lanka.
Must have been an interesting and smelly trip.
