ZA398 still resides at Manston following the birdstrike in January.
The same airframe was also diverted into Manston in late 2013, again with a birdstrike. It has been reported that it won't fly again due to high hours and the cost of repair. The tail might be transferred to another jet apparently.
I personally have always seen the commercial future of Manston as a cargo airport rather than passengers, but it does appear that it's time has come.
The airport released a statement today saying that flight operations are not viable after 9th April - well within the 45 day "consultation" period. Staff cannot be made redundant until the end of the 45 day period though according to the local TV news tonight.
The BBC have tried to book a KLM scheduled flight in April and say that it's not possible to buy a ticket for anything after 8th April.
