BP Latest Attempt to Stop Oil Leak

The latest attempt by BP to stop the oil leak in the Gulf of Mexico is to saw off the top of the pipe and try to cap it.The problem is the saw got stuck.They are trying to change angle of cut to free blade or they may possible have to change the blade.If they get the pipe cut successfully it will probably leak worse for a short period(hopefully) until they get the cap on it.I pray that this attempt will be successful.
