Mark D we are not talking floors here (and yes the J floor was a cock up - but a decision the Movers liked!!!) What is now on the cards is a replacement for the good old MSP now that sense has prevailed and the equally ancient type 5 platform has been proven to be useless - cheap but useless.
But why is the new system going to be limited to 11.3 tonne when the A400M is being designed for a 16 tonne platform? (Why did they let the union of Air loadmasters kill the HSP?)
Now the C-17 has a good (great) floor but its designed around Yank heavy drop techniques and not the far superior UK method of RME MSP/HSP.
OK I'll admit I'm a bit biased.
