Please don't think the RAF have any spare snow clearing capability - the only places that have it are the QRA stations and MEDAs - the rest have to wait for it to thaw or shovel it by hand.
All capability ditched several years ago to save money.
This country has gone to the dogs.
Back to LHR, aside from the lack of rapid snow clearing capability, the treatment of passengers has been at best shameful. Who in the world would want to use the UK as a hub when our largest and most prestigious airport consists of a marquee, kids and babies outside in the cold, people of all ages and backgrounds camping on the floor for 4 days and the Sally Army giving out tea and space blankets.
It doesn't need a board resignation, it needs a public inquiry, the whole business is a disgrace on this once great industry.
