Converting a pair of 747-8 jumbo jets to state-of-the-art luxury command centers by 2024 had been estimated to cost $3 billion when Boeing was picked for the job in January 2015, but since then costs have apparently been rising. "Boeing is building a brand new 747 Air Force One for future presidents, but costs are out of control, more than $4 billion. Cancel order!" Trump tweeted.
Syria's army seized key ground Tuesday in its battle for east Aleppo, capturing more districts and penning rebels into less than a quarter of territory they held in mid-November. The advance came as Moscow and Washington traded barbs over stalled efforts to end fighting in the city, where forces loyal to President Bashar al-Assad have made significant advances since last week. On the humanitarian front, German Chancellor Angela Merkel said it was a "disgrace" that the international community had been unable to alleviate the suffering in east Aleppo.
