A massive fire has ripped through at least two residential buildings in the Swan area of the Persian Gulf city of Ajman in the United Arab Emirates.
According to local media, citing emergency services, the fire has been brought “under control.”
Social media users posted images and footage of the fire late Monday showing bright yellow flames engulfing a building with chunks of burning debris falling to the ground.

We thought we've seen it all when it comes to these drones but they haven't ceased to amaze us just yet. Now they are capable of building a rope bridge - one strong enough to support a person crossing it!, as seen here in this video at the ETH Zurich Flying Machine Arena...
The vehicles are equipped with a motorized spool that allows them to control the tension acting on the rope during deployment. A plastic tube guides the rope to the release point located between two propellers. The external forces and torques exerted on the quadrocopter by the rope during deployment are estimated and taken into account to achieve compliant flight behavior. The assembly of the bridge is performed by small custom quadrocopters and builds upon the Flying Machine Arena, a research and demonstration platform for aerial robotics. The arena is equipped with a motion capture system that provides vehicle position and attitude measurements. Algorithms are run on a computer and commands are then sent to the flying machines via a customized wireless infrastructure.
In order to be able to design tensile structures that are buildable with flying robots, a series of computational tools have been developed, specifically addressing the characteristics of the building method. The design tools allow to simulate, sequence, and evaluate the structure before building.
The location of the scaffolding structure is manually measured before starting the construction. The primary and bracing structure can then be realized without human intervention. Before realizing the stabilizers, the locations of the narrow openings of the bridge are measured and input to the system, which adapts the trajectories accordingly.
