What happens if a bird flies into a plane engine? The event is called a bird strike. Each year, bird strikes cost US airlines an estimated $1.2 billion. Only part of those costs are from actual damage. The rest comes from flight delays and cancellations.
A bird strike can disable a plane's engine. But engines are designed to withstand at least one bird. Plus, pilots can still fly a plane with just one operating engine.
As a result, the chances of an accident are slim. Between 1990-2015 there were 160,894 bird strikes on US aircraft. Only 0.025% of those strikes resulted in an accident.
Despite the low risk, a bird strike can be a shocking experience.
Expect more bird strikes from July to October. That's when over half of them occur each year. Most bird strikes happen during takeoff or landing. They're also more likely to occur during the day than any other time.
Now, if only there was a way to let the birds know.
The FAA requires that every airplane can be fully evacuated in 90 seconds or less. Meaning a flight crew only has 90 seconds to direct passengers to emergency exits. To prepare for a potential evacuation, flight attendants ask passengers in emergency exit rows to lift up their window shades before takeoff and landing.
"If there's an emergency, we have to be able to look out the window to assess outside conditions. If there is debris, fire, or water blocking the window, we won't use that exit and will direct people elsewhere. It may seem like a small thing but in an emergency every second counts. You don't want to have to fiddle with a window shade when you're trying to safely evacuate a plane in 90 seconds."
After a long, tiring flight the last thing you want to do is have to stand around and wait for your suitcase on the luggage carousel.
But a baggage handler has revealed how you can make sure that your luggage always comes off first - and it's all to do with how early you get to the airport.
“Your best option is to be one of the last passengers to check your bags,” Thomas Lo Sciuto, a ramp worker at a regional airport in the US, wrote on Quora.
“Bags will always be loaded front to back on the bag carts so if you check in last, your bags will be in the last bag cart, which will make them the last on the aircraft, and then the first off the aircraft at your destination.”
Lo Sciuto says the same logic applies in reverse: check in first and your bag will be last off.
But if waiting to check in at the last moment isn't an option, Mr Lo Sciuto says there's another trick you can try.
He explained: 'You can also gate check your bag so it will go on last.
'The downside of that method is that you will not be able to pack liquids or any other items that cannot go in a carry-on bag as you will need to bring the bag with you through the security checkpoint and to the gate.
But if your bag is too big to go through security, there is one other trick you could try.
According to Travel + Leisure, you could ask the check in agent if they will put a fragile sticker over your bag.
根据《慢旅Travel + Leisure》杂志报道，你可以问问安检人员，是否可以给你的行李贴个易碎标签。
This is because luggage with these on are also often loaded last with more care taken over them.
