Five science rockets wait for weather to clear

NASA has rescheduled the launch of five suborbital sounding rockets from the Wallops Flight Facility in Virginia to Monday night with liftoff set between midnight and 5 a.m. EDT.

The rockets are part of the Anomalous Transport Rocket Experiment, a mission that will gather information needed to better understand the process responsible for the high-altitude jet stream located 60 to 65 miles above the surface of the Earth.

As part the mission, the five rockets will release a chemical tracer that will form milky, white clouds that allow scientists and the public to "see" the winds in space.  These clouds may be visible for up to 20 minutes by residents from South Carolina to southern New Hampshire and Vermont.

Another day of delays and cancellations for Air Canada

Although Air Canada ground handling employees at Toronto and Montreal international airports have returned to work following an illegal work stoppage this morning, delays and cancellations of Air Canada-operated flights primarily to Canadian and U.S. destinations are expected for the remainder of the day, the airline said in a press statement on Friday.

"We recognize that many customers are being inconvenienced and our focus right now is on getting them to their destination safely, and as quickly as we can," said Duncan Dee, Air Canada’s Executive Vice President and Chief Operating Officer. "We thank our customers for their patience and loyalty as we work doubly hard to restore their confidence in Air Canada. We would also like to thank those employees who worked tirelessly throughout the night to minimize impact on our customers."

Air Canada is the country's largest domestic and international full-service airline providing scheduled and charter air transportation for passengers and cargo to more than 180 destinations on five continents.

Customers are requested to check the status of their flight at aircanada.com before leaving for the airport.

On Sunday, a fire at Lester B. Pearson International Airport in Toronto caused major flight delays and cancellations in the morning for Air Canada and other air traffic. The fire disabled the lights on runway 05/23 and reduced the airport's operating capacity, airport officials said.
