Technical Alternatives for Pitot Tubes?

[greek-freak]

Given that pitot tubes apparently play some role in the Air France accident,
I was wondering if there are technical alternatives to pitot tubes.
To the non-expert it's rather surprising that redundancy for measuring such
important parameters is not implemented via at least one additional device
that uses a different technique and may be less susceptible to
icing/contamination etc.

So my question to the tech gurus is whether there exists an alternative.

Thanks
