minus a wheel... but nothing serious!

[probes]

A wheel fell off an Air Canada plane during takeoff
Pilots were able to turn the Dash 8-300 around and land safely.
"The experienced pilots maintained complete control of the aircraft," Manon Stuart, a spokesperson for Jazz Aviation, the operator of the flight, said in a statement.
"Our pilots are well trained to deal with such situations and responded according to our standard operating procedures. "

Are there sensors to indicate a wheel lost?

I believe that a passenger provided photographs.

One of the 49 passengers on board captured video of the wheel detaching from the plane's left main landing gear and shared it on social media.

Probes, the normal procedure is for ATC to mention it

But seriously, at night, it might not be noticed. A wheel departing at rotate will have some energy and really nothing to stop it.

Interesting shot of that wheel bearing letting go. Probably just as well it fell off when it did. It might have caused a fire when the gear retracted and then fallen off during the emergency landing to really make the crew's day!

Apparently they found the offending wheel in Calgary

Bouncy, bouncy.

I remember a Vulcan lost a boggie pair at Coningsby, Alison might remember, it was late 63 or 64. Heavy landing and off it went, not directly down the runway but bounced off to one side bouncing over the nuclear armed aircraft on Alpha dispersal.

I was about 6 and sitting in a car when we noticed a wheel bouncing cheerfully on the left, and someone even managed to ask: "Wow, whose wheel is that?" before we went to the ditch and it became painfully obvious whose it was...

A guy on my basic flying training course had the same thing happen to him. He asked himself the same question also!
He was lucky enough to be on a long, straight stretch of wide, empty highway and was able to gently edge the vehicle onto the hard shoulder, remembering not to use the brakes.

Just shows the free energy in a wheel

yep - what would they be capable of without the burdens on their backs?

Runaway wheel.....

[TheGreenGoblin]

The best behaved wheels are Australian...

Is there a BBC rule that you must have a mixed race couple on any show?

Back in the early 1950's they built a railway to a point 350 miles north of here to exploit the iron ore deposits in the area.* They were using a Lancastrian to haul cement for a dam to be used to power the project. The strip was gravel, and one day the Lancastrian was lost when it lost a wheel on landing. Years later during a ceremonial elbow bending I asked the pilot about it. He said "I knew we were I trouble right after touchdown, when I saw a main wheel bouncing down the strip ahead of us."

*Hammond Innes' novel "The Land God Gave To Cain" is set in the area.
Don McVicar owned the Lanc, he wrote "The Railroad From The Sky" about the entire railroad construction project. Worth a read - both books - if you can find 'em.
