Orchid trying to escape

Most are aerial roots but not all.

I did try 'staking' it but the stake is only tied to the 2 old stems. It would have helped if the flowering stem had been tied as well but I think it would still have keeled over. The total length of the stem is 3'6" as it is a shoot off a previous flower stem. I think in future, I'll cut all the old stems out so it can't do this again and make sure the new stem is tied to the stake (and burned if it tries to escape again).
