- On Saturday, a Virgin Atlantic plane and a United Airlines plane reached speeds over 800 mph.
- These are some of the highest-known recorded speeds for passenger flights.
- Near record-breaking winds are to blame.
On Saturday, two flights arrived at their destinations early.
A Virgin Atlantic flight from DC to London landed 45 minutes ahead of schedule. Meanwhile, a United Airlines flight from Newark, New Jersey, arrived in Lisbon 20 minutes early.
The passengers have strong winds to thank for that.
High-altitude winds over the Mid-Atlantic helped the planes surpass speeds of 800 mph, The Washington Post reported.
According to Simple Flying, passenger planes typically have a cruising speed of around 600 mph.
The planes flew faster than the speed of sound
The National Weather Service in the DC area reported that the winds reached speeds of 265 mph.
This evening's weather balloon launch detected the 2nd strongest upper-level wind recorded in local history going back to the mid 20th century! Around 34,000-35,000 ft, winds peaked around 230 kt (265 mph!). For those flying eastbound in this jet, there will be quite a tail wind. pic.twitter.com/0MXK0HvsCV

According to NPR, the highest recorded wind speed in the area reached 267 mph in 2002. This makes Saturday's winds the second highest in the region.
Contrasting temperatures often cause strong winds, which is what happened on Saturday. According to The Washington Post, cold air from the Northeast and warm air from the Southeast led to the winds.
These winds pushed Virgin's Boeing 787 to a ground speed of 802 mph and United's Boeing 787 to 838 mph.
The speed of sound is 767 mph. While they were flying faster than the speed of sound, the planes didn't break the sound barrier, The Washington Post reported.
That's because the planes were still flying at their typical cruising speeds — they were just flying in unusually fast air.
While there isn't an official record of top ground speeds, the two Saturday flights are two of the highest known recorded speeds, The Washington Post reported.
Some of the other top recorded speeds include a China Airlines flight that reached 826 mph over the Pacific Ocean last month and a British Airways flight that reached 825 mph in 2020.
