Úvaly Railway Bridge. The Úvaly Railway Bridge (, also known as Devět kanálů) is a railway bridge in Úvaly in the Czech Republic. It is located on the Prague–Kolín railway line.

The structure is  long, built in a slight arc over the valley of the Výmola river. The bridge was built in 1844 out of sandstone and granite blocks, reaching a height of . This section of the railway line between Pardubice and Prague was entrusted to chief engineer Jan Perner, who designed the bridge. A second concrete bride was built  away from the structure in 1954–1955, due to an expansion of the line, the addition of a third track to that section of the railway.

Since 2008, it has been a cultural monument of the Czech Republic.

Ghost flight (commercial aviation). In commercial aviation,  ghost flight is a term used to describe a flight operated by an airline on a regularly scheduled route with an aircraft containing less than 10% of the airplane's total capacity. While initially considered to be a rare occurrence, ghost flights have become more frequent as of the early 2020s following the COVID-19 pandemic. Critics say these flights are unnecessarily adding to the environmental effects of aviation

Since the beginning of 2019, over 5,000 aircraft have flown to and from United Kingdom airports with no passengers. In addition, the Civil Aviation Authority (CAA) confirmed that over 35,000 flights had less than 10% of passenger capacity.  The United Kingdom's biggest airport, Heathrow, accounted for 10,467 flights.

As the COVID-19 pandemic began to spread worldwide in March 2020, flights got cancelled and delayed due to travel restrictions. During this time, airline travel was reduced by 45% in 2020. Because of this, airlines had to increase the number of empty flights in order to maintain their airport slots during this time.

Airport slot rule 
In order to maintain an effective airport and keep flights on time, airports have implemented slot rules to ensure flights are able to continue in a timely manner and limit airspace congestion. These slot rules also help maximize competition and keep airfares low. Airlines are required to utilize the slots for flights or trade them. If a slot goes unused, the airline must give back the slot so other airlines are able to use it.

Before the COVID restrictions, airlines were required to use their allotted spots at least 80% of the time. During the pandemic, the European Commission temporarily suspended Europe's airport slot rule for a short period. Due to travel restrictions, many flights were cancelled or had limited capacity, which made it difficult for airlines to fulfill all the requirements for possessing an airport slot. The suspension of the slot rule was reinstated in October 2021. After the slot rule was reinstated, the rule only required European airlines to use 75% of their flight slots for the winter season. In the summer of 2023, they plan on getting back on track to pre-pandemic regulations and will be required to fill 80% of airport slots. However, in January 2022 the Lufthansa Group, Europe's second largest airline, estimated that it would need to operate 18,000 ghost flights this winter to be able to keep all their current runway slots. Ghost flights are an example of wastage and unnecessary emissions, and are used as an argument for slot reform.

As of July 2022, the European Commission adopted a proposal that would allow more flexibility of airline slots. Airlines would be allowed to use exceptions in situations such as natural disasters, epidemiological emergencies such as pandemics, or widespread political unrest resulting in disruptive effect on air travel. The proposal went into effect on October 30, 2022.

Swan 58. The Swan 58 is a Finnish sailboat that was designed by Germán Frers, with the interior design by Misa Poggi. It was intended as a blue water cruiser and first built in 2020.

Production
The design has been built by Oy Nautor AB in Finland, since 2020. The first hull was removed from the mould in April 2020.  it remains in production.

Design
The Swan 58 is a recreational keelboat, built predominantly of vinylester vacuum-infused glassfibre with carbon fibre reinforcement and with wood trim, including a teak faced deck. It has a fractional sloop rig with a bowsprit, with three sets of swept spreaders and carbon fibre spars. The hull has a plumb stem, a reverse transom with a drop-down tailgate swimming platform, dual internally mounted spade-type rudders controlled by dual wheels and a fixed fin keel with a weighted bulb, deep draft keel or shoal-draft keel. A bow thruster is mounted forward. It displaces  empty and carries  of ballast.

The boat has a draft of  with the standard fin keel,  with the deep draft keel and  with the optional shoal draft keel.

The boat is fitted with a Swedish Volvo D3-150 diesel engine of  for docking and manoeuvring. The fuel tank holds  and the fresh water tank has a capacity of .

The boat is available with a number of different interior arrangements, with three or four cabins. A typical three cabin design has sleeping accommodation for six people, with a double island berth in the bow cabin, a U-shaped settee plus two seats in the main cabin and two aft cabins, each with two single berths. The galley is located on the port side just forward of the companionway ladder. The galley is C-shaped and is equipped with a four-burner stove, a refrigerator, freezer and a double sink. A navigation station is opposite the galley, on the starboard side. There are three heads, one for each cabin.

For reaching and sailing downwind the boat may be equipped with a  gennaker or a code 0 sail. The design has a hull speed of .

Operational history
In a 2020 Sail Universe review noted, this is "a proper bluewater yacht, with all the features for this purpose, but without any compromise in terms of performance."

In a 2021 introductory article for Yachting World, Rupert Holmes wrote, "the cockpit looks beautifully uncluttered, with a clear passage from the transom and helm stations to the companionway. On the other hand some will be disappointed by the positioning of winches and clutches outboard of the cockpit benches, rather than inboard on pedestals ahead of the wheels."

In a 2022 Yachting World review, Rupert Holmes noted, "Nautor is billing the Swan 58 as a 'new bluewater concept'. The idea is that the priorities of safety, comfort and autonomy don't compromise performance, or the pleasure of helming the boat. This model is also pitched as a proper bluewater cruiser that a couple can reasonably sail and look after themselves, without a professional skipper."

Aer Lingus Flight 328. Aer Lingus Flight 328 was a flight operated by Aer Lingus between Dublin Airport, Ireland and East Midlands Airport in the UK. Flight 328 of January 31, 1986, experienced a crash. There were 36 people in the flight, 33 passengers and three crew. On 5:25 p.m. on January 31, 1986, the aircraft launched from Dublin Airport. Upon launching, the aircraft encountered ice. A few hours later, the aircraft started tilting sharply, then, it decreased until it went down and crashed into a field. Most of the passengers sustained no injuries.

Background

Aircraft 
The aircraft type was a Short 360. It had a total of 3226 flight hours.

Passengers 
The flight contained 36 people. 33 were passengers and three were crew members. The captain had a total of 7,528 total flying hours and 123 hours on this aircraft type; respectively, and the co-pilot had 4,299 total flight hours and 1,240 hours on this type.

Flight 
Just before the flight launched, there was a pre-flight briefing, where they discovered that, at the destination airport, the precision radar was damaged. The weather was relatively icy, with a possibility of ice when flying into clouds. The flight launched on 5:25 p.m. on January 31, 1986, with a path from Dublin Airport to East Midlands Airport. They tested the de-icing system during the flight. After a bad flight, they were instructed to descend to . Then, ice was heard striking the aircraft, though the pilots didn't see any ice. Finally, the descent was initiated to about .

Crash 
When the aircraft descended, it rolled sharply to the left. The rolls continued for 30 seconds, increasing. The pilot thought that the aircraft would roll sharply to its back, until the twists decreased. Then, the aircraft suddenly went faster down until it hit a power cable. A passenger reported sparks, from which he thought originated from the power cable. It hit another cable, until stopping at a barley field. No fire was reported. The aircraft's cockpit and passenger cabin were relatively undamaged, but one wing broke off and the other was badly damaged. The aircraft was subsequently written off. Most of the passengers left with minor injuries, with some sustaining cuts and bruises. One passenger hurt their back, and another suffered a broken wrist. A fireman was hospitalized overnight following a motor accident while speeding towards the scene.

Aftermath and investigation 
According to sources, rescuers were "amazed by the passengers' safety" when they expected a bigger crash. The local Civil aviation authority started an investigation to identify what caused the crash. A report stated that the probable cause was the collection of air-frame ice, causing the aircraft to be unstable. Other factors included turbulence, and lack of vision at night, causing the ice to be unnoticed.

2023 Caribbean heat wave. The 2023 Caribbean heat wave was one of the heat waves in the series of the 2023 heat waves. It was an intense weather event characterized by prolonged record-breaking temperatures affecting the Caribbean, South Florida, and the Gulf of Mexico.

History 
On June 6, 2023, a high-pressure system from east of Puerto Rico combined with dust from the Sahara, increased humidity, and record-breaking Atlantic temperatures (likely exacerbated by climate change) to form a heat dome, which drove the local heat index to historic highs.

In early June 2023, a LUMA Energy power plant failed during high demand, causing a power outage that affected over 100,000 people in Puerto Rico. LUMA Energy urged customers to conserve energy, and most of the service was restored by June 7.

Statistics 
The heat index surpassed  in some areas, with extremes of  in northern Puerto Rico. High temperatures continued overnight. San Juan set a record-high minimum of  for three consecutive nights. Additionally, the island of Saba reported a record , and Aruba reported . Sea temperatures also reached record levels in areas over the Atlantic Ocean. On June 7, an excessive heat warning was issued for north-central Puerto Rico and a heat advisory in other areas.
