Endplay,
The Mk3 Chinooks were built with an anologue cockpit in Philly, flown to Shreveport for the Glass Cockpit and thence to the UK. They are now being re-fitted with the analogue cockpit and sometime in the next 5 years will receive another Glass cockpit under the auspices of Project Julius (which is similar to the one it would have got under fix to field...).
Compared to c£5bn for 9 MRA4s they STILL seem good value.....
