Israel launches military offensive against Gaza
JERUSALEM (AP) — Israel launched
what could be a long-term offensive against the Hamas-ruled Gaza Strip
on Tuesday, the military said, striking at least 50 sites in Gaza by air
and sea and mobilizing troops for a possible ground invasion in order
to quell rocket attacks on Israel.
The
army said its offensive, dubbed "Operation Protective Edge," is aimed
at striking Hamas and ending the rocket fire that has intensified in
recent weeks amid tensions over the killing of three Israeli teenagers
and the apparent revenge killing of a Palestinian teenager.
Could P. sandersi fly?
To find out how P. sandersi could
take off and stay aloft despite its giant size, Ksepka fed data about
the bird's mass, wingspan and wing shape into a computer program
designed to predict flight performance. The researchers estimated the
bird weighed from 48.2 to 88.4 lbs. (21.9 to 40.1 kilograms).
Giant bird, giant dig
The specimen was so large that
it had to be dug out with a backhoe. "The upper wing bone alone was
longer than my arm," Ksepka said in a statement.
World's Largest Flying Bird Was Like Nothing Alive Today
The largest flying bird known to ever have lived has now been
revealed, an extinct giant with a wingspan more than twice the size of
the largest living flying bird, researchers say.
