interleaving? table rows in oracle

hi, i have an oracle 9i table (called Vehicles).

it has 3 columns (vehicle_id, measurement_1, measurement_2)

i'd like to create a view from this table that "interleaves" the values of measurement_1 and measurement_2.  not sure if "interleave" is the right verb and google hasn't helped.

e.g. the vehicles table's rows might look like this (values separated by commas):

1, 55.2, 58
2, 80, null
3, 40, 42
4, null, 18

i'd like the resulting view to display

1, 55.2
1, 58
2, 80
2, null
3, 40
3, 42
4, null
4, 18


which essentially "merges" the 2 columns called "measurement_1" and "measurement_2"

i feel like this is going to be a head-slapper when I finally figure it out, but right now i'm stumped as to how to merge these 2 columns into 1.

any ideas?
thanks!
