Security at times struggled to hold back a huge throng of reporters who made it difficult for the families to enter or exit the room. 07:46 GMT - My colleague Neil Connor at the Lido Hotel, near Beijing airport where relatives and friends of the passengers were taken, as spoken to some of the people there. "They should have told us something before now," said one man at the hotel, who was in his thirties and from the northern Chinese city of Tianjin. The man, who was visibly distressed, did not say who was on the airplane that he came to meet. Another man, who was also in his twenties, struggled to help someone who appeared to be his grieving mother into a quiet room, as journalists tried to interview her. He then angrily said: "We haven't been told anything about this. They (Malaysia Airlines) are useless. I don't know why they haven't released any information." 07:33 GMT - China ships - China's State Oceanic Administration says it has ordered maritime patrol vessels conducting missions nearby to head to the area to join rescue efforts. 07:32 GMT - Figure change - The airline has tweaked it's nationality figures again.

Three people died. "We're closely monitoring reports on Malaysia flight MH370.

We are doing all we can to get more details." 06:48 GMT - Crew needed - Aviation analyst Gerry Soejatman explains that even modern planes still need the crew to make decisions. "If the crew is not on the ball, they quickly lose control of the situation and themselves and end up in trouble.” “Modern planes are safer, but you still need the crew to make the decisions. The technology is to ease their jobs, and not to replace them." 06:37 GMT - 12 hours - It is now nearly 12 hours since contact was lost at 2:40 am Malaysian time (1840 GMT Friday) Search and rescue 06:26 GMT - Ships sent - Faridah Shuib, a spokeswoman for the Malaysian Maritime Enforcement Agency says Malaysian authorities have dispatched a plane, two helicopters and four vessels to search seas off its east coast in the South China Sea.

He said there was “nothing abnormal” about MAS’safety record. “On the maintenance side there is nothing. Even on the rumour mill there is nothing drastic, of course in the workplace there are always problems. There is nothing that would jump out straight out of the page.” 06:04 GMT - "Golden window" - Indonesia-based independent aviation analyst Gerry Soejatman, speaking to my colleague Roberto Coloma from Jakarta says search and rescue efforts have to work within a “24-hour golden window.” “You can’t assume that there are no survivors, and if there are any, it is absolutely crucial that they are picked up within a day, or the chances of survival drops significantly.” “Airline pilots are not trained in crash landings in the sea, but they are taught the techniques. Both the pilots and the cabin crew are also taught the survival skills necessary in such situations.” 05:49 GMT - Search area - The important thing now for officials is to locate exactly where the plane may have gone down to narrow the search area. The Vietnamese government on its website has already said the plane lost contact in Ca Mau province airspace before it had entered contact with Ho Chi Minh City air traffic control.
