Aircraft storage? Ah yes - just as we did with some VC10Ks at that well-known low-humidity, low salt environment.....RAF St Athan.

Then 'They' decided they needed one back for one of Bliar's 'bring a bottle and come as you are' Balkan wars.

So in April 1999 I went to fly the airtest on a 'stored' VC10K2 after Scrapheap Challenge had found enough engines and had mopped out most of the rainwater. In flight we had the "It'll never happen" loss of #1 & #3 busbars whilst doing shut downs and relights. Shutdown #3 engine, then # 1 alternator had a think about things before deciding "This is too much" and tripped - but didn't do so cleanly. So the system protected itself from cascade failure and we ended up with no attitude systems (are you listening, Haddon-Cave, this is a design consequence of fitting a HDU to the VC10K without including a polyphase start set), masses of warning lights and failure flags...and a rising cabin altitude. Restarted #3 and got #1 and #3 busbar back with their associated PFCUs, diverted to Brize. Where they found that all the sea water which had gathered in the bilges during 'storage' had corroded a voltage regulator.

Went off a couple of days later to do the rest of the air test; all OK until ELRAT drop when the voltage and frequency went nuts on the approach and smoke appeared on the flight deck. Smoke drill, throw it on the ground and give it to the engineers - yet another corroded voltage regulator, this time it was the ELRAT's.

Eventually they managed to fix it; we ended up using it for normal duties and released another jet for Bliar's war. Within 2 years it had been scrapped....
