I bet a number of the Leasing and Spot Hire Co's are kicking themselves today - Porterbrook and the ex Chiltern Mk3s, ROG for letting go of the 47s, Eversholt for the 321 scrapping etc. A lot of companies and groups have been contacted today.
They might be kicking themselves, but then again storage isn't free and fleet groundings are (fortunately) not all that common!
