DG800 - The RAF can't take any risks as they are flying someone's kid in the Grobs and after the summer a couple of years back they are over safe with good cause.
Can you imagine the uproar if one did go in and the fleet hadn't been grounded? The fleet are dispursed around the country and it takes time to get the manpower in the correct place.
May be an over reaction but better that than learn from hindsight.
