Well this could have gone terribly wrong altogether.
A passenger on a London tube train over the weekend had a rather unusual journey when the doors failed to close after a stop. Rory Brown posted the video to Twitter following the event:
@TfL new way to keep tubes cool in the summer - leaving the doors open 🙄 pretty bloody sketchy! #whatishealthandsafety? pic.twitter.com/ntQC0hNgL0

Rory also claimed there was "at least 10 different doors" open during the incident.
Transport for London responded to Rory's tweet and also confirmed that "some of the doors" on a Jubilee train remained open for "one stop between Finchley Road and West Hampstead" in north London on Saturday, September 1 at around 0900.
Hi Rory, we were made aware of this yesterday and the train was taken out of service and currently under investigation so thanks for letting us know. Sorry for any inconvenience caused and hope your journey was okay. Thanks - Dan

While Nigel Holness, the network operations director for London Underground, said in a statement: "The safety of our customers is our top priority.
"The train was immediately taken out of service at West Hampstead and a full investigation is underway to understand how this occurred."
Thankfully, no-one was hurt or injured during the incident.
