1. There was water on the runway. If more than 3mm, larger chances for planes to skid. Mumbai run way was under way MORE water than that.
2. The runway rubber marks that tyres make when planes touchdown, make the runway slippery. These are supposed to be removed during maintainence on a regular basis. 400%, that this was NOT being done at Mumbai - that airport doesn't have breathing space, landing some 600-800 flights a day !!!
3. This spicejet crash happened when the plane was exiting the runway still at good speed onto the taxiway, skidded out of the runway onto the gutter and soft mud next to the runway. Most likely bad weather conditions responsible.
Sorry boss, it wasn't 'exiting' the runway at good speed. BOM does not have a rapid exit taxiway. The only plausible speculation is that the flare was longer than permissible, the thrust had been put to idle however. What irks me is that the airport promoter expects airlines to have a removal kit (giant airbags), Air India is the only airline with an operational kit that was being used at IXE to remove the stranded AI Express. Its been 3 days and the main runway is still not operational leading to a delay index average of 45 mins, an several cancellations and fuel limitations.
Err...BOM is the busiest single runway in the world with over 50 movements an hour and you wouldn't be able to get there without RETs. On its way off the runway, the SpiceJet plane shot past 3 of them.
Secondly, it is standard practice to have Disabled Aircraft Retrieval Kits with one designated carrier in a given region. In our case it happens to be AI, the national carrier. They are not doing any favours to anyone as claimed by certain 'experts' such as Mohan Ranganathan or some airliners.net or SSC fanbois. There's no free lunch anywhere and aviation certainly is no exception.
The DGCA says...
Whereas it is economically impossible to store all the equipment necessary for the removal of disabled aircraft, it has been generally agreed that the most feasible approach to the problem is for the airport authority to prepare a plan for each airport, in consultation with operators, for the removal of a disabled aircraft and to make arrangements with other agencies for the pooling of specialised equipment required. To overcome the problem, the major airlines have already made arrangements so as to make specialised equipment available on short notice on a world-wide basis and the kits have been strategically placed around the world.
The responsibility of removing a disabled aircraft lies with the operator concerned who will bear all costs incurred in the removal operation. The airport authority is, however, required to establish a pre-arranged plan in agreement with the operators and other assisting agencies for expeditious removal of disabled aircraft.
Aircraft belong to the airline and they wouldn't appreciate even the airport operator touching their planes. it's either the airline themselves or their designated ground handlers who work on the aircraft.
