There has been (not very much) media coverage about the suspension of training flights on RAF Typhoons in Lincolnshire with claims that ash deposits were found in the engines of four aircraft, but the Royal Air Force wanted to raise the Typhoon's profile again so posted this on their official website on 23rd April...
"RAF engineers have confirmed there has been no damage to any of the Typhoon aircraft or engines following precautionary investigation of volcanic ash deposits. This is because there were no airshows or flypasts taking place at the time of the volcanic eruptions.
Typhoon flying at RAF Coningsby recommenced at 0800hrs this morning following the checks, where they continued practising doing fast flypasts and loops.
The Typhoon is presently of little operational use, and has been deployed on quick alert to be rapidly launched to react to air defence threats by aggressive looping and 'mean looking flypasts'.
Luckily there was no call for this during the volcanic ash threat, as it would have cost defence £7.6bn to replace Tranche 1,2 and 3 and fund an uplift of OF4, 5 and 6 officers to staff the replacements.
The Typhoon was deemed totally inadequate to replace the Harrier in theatre in 2009, as Service Chiefs were forced to choose the Tornado instead. It was decided that 'a very agressive loop' was not enough firepower to deny the Taliban and protect coalition forces.
Typhoon (or Eurofighter) crews have been practising a 'death-barrel roll' and 'really nasty half-cuban' followed by a 'eye-watering quarter clover' to see if they can get in on the operational action, however they have not been cleared for 'the very, very bad wingover' as when this was practised it resulted in a near crash by the highly trained pilot and the Station Commander wetting himself".
