Pardon my ignorance, but I have never heard of this incident. When/where was
that? If this happened before the A320 crash in Warsaw, it would be amazing
that the logic preventing this type of accidents wasn't built into Airbus'

I recall hearing somewhere that, unlike later -300 and up versions, the
737-200 has to have all wheels on the ground (front too) for the thrust
reversers to be activated, simply because there is a possibilty of the
reversers touching the runway when the front wheel is still up.

Could anyone verify that?
