DC10, I reckon it will be even sooner than that, more likely 18 months to 2 years. With the relatively high turnover of support staff - HR etc getting a few years experience with a major organisation and then moving on - the likelihood of new members outnumbering old members is failrly high. The only major stalwarts of the old scheme will be the ATCO's, and the ATSA's and Engineers (at least those that are left after the move of MACC to PC and any redundancies that will be made from the introduction of whatever new off the shelf time and money saving [or should that read time and money wasting] systems they decide to bring in).
